Abstract
The invention relates to a synthetic grey-white jade and a manufacturing method thereof. The synthetic grey-white jade is manufactured by adopting the steps of: mixing and milling sodium oxide, aluminum oxide, silicon oxide, magnesium oxide, phosphorus oxide, potassium oxide, zinc oxide, beryllium oxide, strontium oxide, boron oxide, lithium oxide and the like; sintering the mixture at a high temperature; carrying out annealing treatment and acidic immersion. The color of the grey-white jade provided by the invention is similar with that of a natural jade, and even more bright, gorgeous and colorful than that of the natural jade; and the color of the grey-white jade can be perpetually constant. The elements including lithium, cerium and the like are added into the synthetic grey-white jade, so that the amount of negative ions generated by the jade is improved. The far infrared wavelength of the synthetic grey-white jade reaches a range within 4.5-6 microns, so that the synthetic grey-white jade is good for human health.
Description
Technical field
The present invention relates to the jade synthesis technical field, relate in particular to synthetic grey-white jade and manufacture method thereof.
Background technology
Natural jade is vitreous luster, gentle and damp, has stronger oilly, gives moist sensation, and the wax sense is arranged under the low light level, and that sees is comfortable, the profit aesthetic feeling of comforting.Jade in China's jade culture is symbols of all spiritual U.S.s such as beautiful, valuable, noble, honest.Along with social progress, the improving constantly of people's living standard, people are growing to the demand of jade, however the resource of natural jade is more and more rare, and limited resources can not satisfy the demands, and market value rises steadily.Synthetic gems is the inorganics of synthetic, and it not only has and the corresponding figure of natural jade, and basic identical at aspects such as physical and chemical composition, atomic structures with natural jade.
The jade product that existing market is sold, a part is the stone of processing through the artificial optimization, surface color, glossiness are similar to natural jade, are difficult to distinguish.The tremolite, green stone that some enterprise will diminish HUMAN HEALTH carry out the acidifying decolouring, immerse chemical color elements, sell after being processed into product, mix the spurious with the genuine, and are difficult to find out the jade of crossing through manual handling from surface.Part jade processing enterprise, adopt the scrap stock of identical jade grade to carry out processing treatment, supplies original damaged color and surface tissue, as: heat treatment, the color of change stone, make it similar to jade; Or, after surperficial acidification, vacuum sucks the element tinting material, surface sucks resin solidification, makes the color light bright-coloured; Or laser treatment adds various elements to change the surface chemistry component content of jade, the jade grade is improved.
More some enterprise is because technical route is different different with the material therefor formula, although the product surface color worked out, glossiness is similar to natural jade,, product contains radioactive substance, and HUMAN HEALTH is caused damage.
Summary of the invention
The technical problem to be solved in the present invention is to overcome defect of the prior art, and a kind of synthetic grey-white jade and preparation method thereof is provided, and this synthetic grey-white jade is not only harmless to people's health, can also send far infrared wave for a long time limitedly, is of value to HUMAN HEALTH.
The present invention is achieved by the following technical measures.A kind of synthetic grey-white jade is characterized in that: its composition comprises: 25 ~ 27 parts, 3.5～3.7 parts of (in mass fraction, lower same) aluminum oxide of sodium oxide, 38 ~ 41 parts of silicon oxide; 7.4～7.6 parts, magnesium oxide, 0.4～0.6 part of phosphorus oxide, 0.3～0.5 part of potassium oxide, 8～10 parts, calcium oxide, 1.4～1.6 parts of titanium oxide, 0.1～0.3 part of manganese oxide, 0.2～0.4 part of ferric oxide, 0.1～0.3 part, zinc oxide, 0.1～0.2 part of beryllium oxide,, 0.1～0.2 part of strontium oxide, 0.4～0.6 part of boron oxide, 0.1～0.2 part of Lithium Oxide 98min Li.
A kind of method of manufacturing synthetic grey-white jade comprises the following steps:
A. the rear mixed grinding of raw material being weighed, granular size≤80 orders;
B. the corundum crucible of the raw material after grinding being packed into, be warming up at a slow speed 1450 ℃-1550 ℃, after insulation for some time, is cooled at a slow speed 85 ℃-125 ℃, after insulation for some time, takes out;
C. grey-white jade is taken out and puts into annealing furnace from corundum crucible, be warming up to 680 ℃-720 ℃, after insulation for some time, slowly automatically take out after cooling;
D. the grey-white jade after annealing is cut, the solution that then to put into pH value be 3.0～4.0 soaks for some time;
At this, mean the precedence of these reactions steps with (A)～(D).
As preferred version, in described step B, the heating-up time is 15～18 hours, and after heating up, insulation is 6～10 hours.
As preferred version, in described step B, temperature fall time is 70～74 hours at a slow speed, and after cooling, within 20～28 hours, as preferred version, in described step C, after heating up, soaking time is 2～6 hours in insulation.
As preferred version, in described step D, in solution, soak time is 5～9 days.
Detection for synthetic Green OnyxB, there is no unified standard at present, can only propose some relative requirements.
1 relative density detects:
Adopt Archimedes' principle, the quality of equal-volume water equals the airborne quality of jade and deducts the quality of jade in water.
Formula:
2 traditional discrimination methods:
Its quality of nephrite is moistened soft, slippery feel, and there is grease-like on surface, and close with the tremolite, color is soft, and light folding rate is better, with strong illumination, reflective sense is obviously arranged.
3 specific refractory poweres:
Measure the specific refractory power that obtains this jade on a polished surface of synthetic gems with refractometer, general all between 1.54 ~ 1.68.
4 hardness:
Adopt Mohs'hardness scale, measure the hardness of jade, instrument direct-reading value gets final product, but requires the mean value of measuring more than three times to be as the criterion.
5 negative ions detect:
Adopt negative ion mineral detector, in the detection casing of setting, the anion direct reading that direct-detection discharges is as the criterion, general 35 ~ 85/cm of jade anion concentration
3, synthetic gems is 50 ~ 125/cm
3.
6 far infrared waves detect:
Adopt the far infrared wave detector, directly synthetic gems is scanned, the emittance of working sample and K value, 3.5 ~ 5.5 microns of general jade far infrared waves, the synthetic gems far infrared wave is 4 ~ 6 microns.
After the present invention adopts abovementioned technology, there is following technique effect.
1. the ratio of the material in can filling a prescription by adjustment, make synthetic grey-white jade color reach the color close with natural jade, even can be more bright gorgeous more colorful than natural jade.
2. synthesize at high temperature long-time heating of grey-white jade, the color be exchanged into through balancing each other can be permanent constant.
3. increase lithium in synthetic grey-white jade, the elements such as cerium, can make the negative ion amount that jade produces improve.
4. synthetic grey-white jade far infrared wave reaches between the 4.5-6 micron, useful HUMAN HEALTH.
