While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Embodiments of the present disclosure provide a method of preparing synthetic surface by a pulverization step in which a plurality of raw materials are pulverized and mixed in a predetermined ratio to obtain a powdery mixture; a mixing step, wherein a sodium metasilicate aqueous solution is added to the powdery mixture and mixed to obtain a paste; a drying step, wherein the paste is heated and dried to obtain a solid block; and a crushing step, wherein the solid block is crushed and screened to obtain synthetic crushed stone and/or synthetic powder, so that the crushed stone generally existing on the surface of the small celestial body can be simulated, pebbles and powdery surface soil with consistent strength are manufactured, and the smooth implementation of the small celestial body detection task is powerfully supported.

Some mineral components present in celestial bodies, such as enriched serpentines, merthiolates, etc., are not present in large quantities on the earth and are difficult to synthesize in large quantities, and in addition, some organic matter, such as tollin, also present in celestial bodies cannot be naturally formed in the environment of the earth. The embodiment of the disclosure selects corresponding substitutes for such substances, for example, selecting magnesium serpentine to replace magnesium-rich serpentine, selecting pyrite to replace merthiolate, selecting humic acid to replace tollin, and the like.
In some embodiments of the present disclosure, the plurality of raw materials includes, for example, any one or more selected from olivine, low-spodumene high-spodumene, albite, pyrite, iron-nickel metal, apatite, serpentine, magnetite, activated carbon, and humic acid, and the selection of a specific raw material and the predetermined ratio of each component are determined according to the simulated target celestial body. The minerals in the raw materials can be natural rocks with the highest purity, and other raw materials can be high-purity industrial products. For example, olivine particles are from olivine trap in north river, low-calcixene is from inner Mongolia Alaran area, high-calcixene is from Shandong flatness area, albite is from Hebei Shijiazhuan area. IRS-1 does not contain the accessory minerals common to the S-type asteroid surface, and the raw materials of the disclosed embodiments may also include apatite and chromite as mimics to the accessory minerals.
For example, the S-shaped minor planet has been shown to correspond to the common spherulite. The common spherulites are by far the most common type of merle falling on the earth, with approximately 80% or 90% of the spherulites being common spherulites. Spherulites are classified into high iron (H), low iron (L) and low iron and low metal (LL) according to the total metal and iron. High iron population (H) refers to high total iron content and high metal content; low iron group (L) refers to low total iron content; low iron low metal (LL) refers to low total iron content, low metal content.
In simulating the S-shaped asteroid, the various raw materials may include olivine, high and low cadithins, albite, pyrite, iron-nickel metal, apatite, and chromite.
As another example, the main belt comet 133P/EP is believed to be associated with the minor planet Themis family or the Beagle subfamily, whereas for the Themis and Beagle family members, the most similar spectra are currently known to be from carbonaceous spherulites, primarily CM-type carbonaceous spherulites, with varying degrees of water alteration. In simulating the type C asteroid, the various raw materials may include olivine, pyroxene, serpentine, pyrite, magnetite, activated carbon, and humic acid.
In some embodiments of the present disclosure, in the pulverizing step, the lump, granular mineral raw materials may be pulverized and sieved into a powder state using a jaw crusher, a disc mill, and a sieve. The average particle size after processing is in the order of one hundred microns. For example, the bulk, granular starting material can be crushed to a median particle size of 50-200 microns, preferably 100 microns, which is slightly larger than the spherulite matrix, is close to or slightly smaller than the size of the spherulite, is suitable for large-scale grinding, and can be economically and efficiently produced into a simulant. The median diameter refers to the diameter corresponding to the cumulative percentage of particle size distribution of a sample of 50%. The powders are mixed thoroughly in the above predetermined proportions to give a powdered mixture as shown in FIG. 2A, which is typically a medium to dark gray powder.
In some embodiments of the present disclosure, in the mixing step, an aqueous solution of sodium metasilicate may be added to the powdered mixture, and stirred to obtain a malleable paste as shown in fig. 2B. Wherein the weight ratio of the powdery mixture to the sodium metasilicate pentahydrate can be 100:2-4, preferably 100: 3-4; the weight ratio of the powdered mixture to pure water may be 10:1-3, preferably 10: 2.
In some embodiments of the present disclosure, in the drying step, the paste is dried by heating to obtain a solid block. Wherein, in the case of synthesizing synthetic surface for S-shaped little planet (including H, L and LL type), the paste can be heated at 150-170 ℃; in the case of synthesizing a synthetic surface for a type C asteroid, the paste may be heated at a temperature of 110 to 130 ℃. If the temperature is lower than the above temperature, it is insufficient to precipitate the sodium silicate polymer; if the above temperature is exceeded, water and other volatiles bound to the serpentine are driven off, causing a change in mineral structure.
In some embodiments of the present disclosure, in the crushing step, the solid block may be crushed by a hand tool, the particle size may be controlled by sieving and changing the duration of crushing and/or the crushing strength, the particle size range, the particle size distribution, etc. of the synthetic crushed stone or synthetic powder may be controlled to obtain a desired synthetic surface, to simulate crushed stones ubiquitous on a celestial surface, as shown in fig. 2C, and a fine grained regolith or soil that should be dominant on a larger minor planetary surface, as shown in fig. 2D. Optionally, the obtained synthetic surface soil at least comprises synthetic macadam with the particle size of more than 1cm and synthetic powder with the particle size of less than 1mm, and the particle size distribution of the synthetic surface soil is 0.01mm-1000 mm. The simulated surface can be screened and the granularity can be adjusted according to the required granularity distribution characteristics.
In some embodiments of the present disclosure, the method may further comprise a pretreatment step prior to the comminuting step. In the pretreatment step, a plurality of raw materials are pretreated and analyzed, thereby selecting a raw material having a purity satisfying a preset condition. The pretreatment can also comprise the steps of cleaning and drying the raw materials and removing surface impurities, so that the components of the minerals are more stable and easier to control, the raw materials are convenient to analyze, and the accurate simulation of the surface soil of the celestial body is facilitated.
One or more of a scanning electron microscope energy spectrometer, an electronic probe, an X-ray fluorescence spectrometer and a reflection spectrometer can be used for analyzing raw material minerals, determining mineral components, quantitatively measuring chemical components and identifying other existing mineral components. The present inventors have found that small amounts of other minerals are found in minerals of natural origin, and that some natural minerals also differ in their crystal chemical structure from those found in merles, e.g., the earth's ore has higher concentrations of Mg and Al and lower Fe content relative to the same mineral in merles. Embodiments of the present disclosure can appropriately select minerals and mixtures thereof according to the results of the composition analysis, thereby enabling an increase in the degree of simulation of the synthetic surface.
In the pretreatment step, the lump or granular mineral raw material may be previously crushed and sieved by using a jaw crusher, a disk mill and a sieve to obtain desired granules or a mixture of granules and powder, thereby improving the degree of simulation of the synthetic surface.

The first comparative example is as follows: the photograph of the surface of the asteroid Sichuan is shown in FIG. 4.
Comparative example two: preparation method of IRS-1
IRS-1 is prepared by first crushing the raw material, passing the coarse (i.e. 0.5 to 5 cm diameter) ore pieces through a jaw crusher to fine (i.e. <0.5 mm diameter) ore pieces as shown in FIG. 5; then, screening and adjusting the particle size, and screening and adjusting the particle size distribution of the crushed mineral according to the designed particle size characteristics (less than 2000 μm, D90 being 1400 μm, D50 being 800 μm, D10 being 100 μm, wherein D90, D50 and D10 respectively refer to the corresponding particle sizes when the cumulative particle size distribution percentage of one sample reaches 90%, 50% and 10%); finally, mixing the mineral components, and mixing the sieved mineral powder according to a preset proportion, wherein the preset proportion is 60 wt% of olivine, 20 wt% of clinoptilolite, 5 wt% of monoclinic pyroxene, 10 wt% of plagioclase, 3 wt% of pyrrhotite and 2 wt% of scrap iron. A photograph of IRS-1 from the prior art is shown in FIG. 6.
Therefore, the maximum particle size of the surface simulant IRS-1 prepared by the preparation method in the prior art is small and is in a fine sand shape, and the morphological characteristics of the surface of the celestial body cannot be simulated, while the particle size of the synthetic surface simulant IRS-1 prepared by the method in the embodiment of the disclosure is distributed in various ranges, and the synthetic surface simulant IRS-1 has a crushed stone-shaped part and a fine sand-shaped part, so that the morphological characteristics of the surface of the celestial body can be well simulated.
In addition, the reflectance spectrum of the asteroid surface reflects its own material composition. For example, the main components of the surface of the S-shaped small planet are silicate and metallic iron; type C is rich in carbonaceous and organic components, similar to carbonaceous spherulites. To better compare whether the mimic fits the meteorite, we performed visible to mid-infrared reflectance spectroscopy measurements on the mimic using an instrument of bruker Vertex70, with a wavelength range of 0.5-25 microns.
FIG. 7 shows a reflection spectrum of synthetic soil A, B, C according to an embodiment of the disclosure; FIG. 8 shows the reflectance spectra of the S-shaped asteroid and common spherulite; fig. 9 shows a reflection spectrum of the synthetic surface D and the main belted comets 133P according to an embodiment of the disclosure. Table 1 shows the small celestial surface soil mimics and the corresponding spherulite treolite component table (wt%). As shown in fig. 7-9, the spectral results show that the synthetic surface has a similar overall trend with the reflectance spectrum of the corresponding celestial or merle, and the spectral morphology matches well with the spectrum of the target celestial body. As shown in Table 1, there was a better similarity between the different mimetics and the corresponding merle.
TABLE 1 Small celestial body surface soil simulant and corresponding spherulite Whole rock composition table (wt%)
In particular, since minerals are analyzed and screened in the pretreatment step, as shown in table 1, in various soil mimics prepared in the examples of the present disclosure, the contents of aluminum, iron, and magnesium are very close to the contents of corresponding elements in natural merle, and have a good simulation effect on the merle, so that it can be considered that the mimics can also better simulate the surface soil of the celestial body.
