Abstract
The invention discloses preparation of colorful high-temperature-resisting siliceous jade by using an electric smelting method. The preparation comprises the following steps: uniformly mixing quartz powder and additives according to a molar ratio of 100:(3-10), drying, grinding and heating to be 1,400-1,800 DEG C in a vacuum electric furnace, keeping the temperature, cooling down to the room temperature along in the furnace, slicing, grinding, polishing, packaging and storing. The preparation has the advantages that the colorful jade produced by using the electric smelting method is uniform in color and capable of bearing burning of high-temperature flame without fading, and meanwhile the process for producing the colorful jade is rapid in production speed and the product quality is stable; therefore, the process is applicable to industrial production of large-scale jade materials. The quartz powder with the mohs' hardness of 5 to 7 and the density of 2.5-4.5g/cm<3> is an ideal raw material for preparing gem-grade jade and craft-grade colorful jade, has excellent high-temperature resistance, is free of deformation and fading in the thermal machining process, and can be widely applied to industries such as high-class accessories and artware.
Description
Technical field
The invention belongs to architectural decoration material field, particularly the electric smelting legal system of the high temperature resistant siliceous jade of a kind of colour is standby.
Background technology
Siliceous jade refers to that chemical composition take silicon (Si) matter and be main a series of jade class jewels, by its genetic type, is divided into natural jewels and jade and artificial gem; Natural gemstone refers to attractive in appearance, durable by nature output, can be processed into mineral single crystal or the twin crystal of ornament, because output is rare and expensive.
Because natural jade resource is fewer and feweri, price is more and more expensive, so people are making great efforts to seek the method for synthetic jade always; Under this background, synthetic gems just arises at the historic moment.This wholly or in part by artificial production or manufacture with the jade material as jewellery and ornament also referred to as artificial jade.
The method of synthetic jewel generally includes the synthetic method of melt crystallization, solution crystallization; Melt crystallization comprises flame melt method, crystal pulling method and cold crucible method.Flame melt method claims again Verneuil method, is the powder of raw material is melted after the oxyhydrogen flame by high temperature, and molten drop is the cooling and formation crystal of growing on kind of crystalline substance in dropping process; Crystal pulling method is to form raw material heat fused in crucible of crystal, at bath surface inoculation crystalline substance, lifts melt composition crystal; Cold crucible method is only limited to production crystal of zirconium oxide.Solution crystallization method be by suitable components dissolved in low viscous liquid, by control condition, make it chemical combination crystallization, produce needed crystal.From the technology of solution crystallization, have two kinds of flux method and hydrothermal methods, wherein the most frequently used is hydrothermal method.
Superhigh-pressure high-temp method is also usually used in the synthetic of precious stone; This method is under high temperature and uht conditions, and the metamorphic mineralization process that in the simulation earth's crust, jewel forms is synthesized, and is usually used in diamond synthesis, emerald etc.
Yet existing have these jewel synthetic methods, all exists processing condition complexity, crystallisation process wretched insufficiency slowly; Meanwhile, the defects such as that the synthetic jade of these methods exists under hot conditions is yielding, variable color, have brought very large impact to the follow-up weldprocedure of gem processing process.
Therefore, by novel process, produce the siliceous jade of high temperature resistant colour and there is higher marketable value.
Summary of the invention
The object of the invention is to solve above-mentioned existing existing problem, provide the electric smelting legal system of the high temperature resistant siliceous jade of a kind of colour standby.
The present invention is achieved in that
1, choose cobalt sesquioxide, titanium dioxide and Red copper oxide chemical reagent as the additive of the siliceous jade of colour;
2, by 100-140 object silica powder and aforementioned additive in mass ratio the ratio of 100:3-10 in batch mixing pond, mix, make the color uniformity of mixed powder.Mixed powder is put into drying baker dries, and takes out after grinding and puts into plumbago crucible;
3, the plumbago crucible that compound is housed is put into vacuum electric furnace.Before heating, must guarantee that body of heater cooling system is working properly, vacuum system is working properly;
4, the temperature rise period: under room temperature to the 1400 ℃ condition that can allow at equipment, carry out the following rapid heating of 50 ℃/min; Within the scope of 1400 ℃-1650 ℃, need control to be less than 5 ℃/min heat-up rate, and keep the following vacuum tightness of 0.01Pa, be beneficial to the smooth discharge of gas between powder, be then rapidly heated to 1750 ℃-1800 ℃ and keep 30-120min;
5, cooling stages: after insulation finishes, cut off heating power supply, carry out furnace cooling under vacuum condition within keeping stove; When being reduced to 1100 ℃ of constant temperature, cooling temperature keep 30min to eliminate due to the quick cooling internal stress producing; After finishing, insulation cools to room temperature with the furnace;
6, the jade after high temperature melting carries out packing and storing after section, polishing and polishing.
Advantage of the present invention is, the colour jade that adopts vacuum electric smelting method to produce has uniform color and luster, can bear that flame high temperature burns and colour-fast.Meanwhile, adopt explained hereafter colour jade of the present invention to have that production rate is fast, constant product quality, be applicable to fairly large jade material suitability for industrialized production;
Siliceous jade prepared by technique of the present invention, mohs hardness is 5～7.Density is 2.5～4.5g/cm
3, be the desirable feedstock of preparing Gem Grade jade and technique grade colour jade, there is excellent resistance to elevated temperatures, hot procedure is indeformable colour-fast, can be used widely in industries such as high-grade ornaments and artworks.
Accompanying drawing explanation
Fig. 1 is the production technological process of the siliceous jade of high temperature resistant colour.
Embodiment
Below in conjunction with example, illustrate:
1, the staining agent compound method of different color: as redness adopts cuprous oxide powder, blue with pure cobalt sesquioxide powder, black adopts titanium dioxide powder; Green cobalt sesquioxide and the titanium dioxide powder mix of adopting, if the two ratio is 3:1;
2, by 100 object silica powders and staining agent in mass ratio the ratio of 100:3-5 in batch mixing pond, mix.Getting the about 500g powder mix of gross weight puts into loft drier and dries.Bake out temperature is 120 ℃, drying time 3 hours;
3, the compound after drying is ground in mortar, make mixed color uniformity.Then compound is put into plumbago crucible;
4, the plumbago crucible that compound is housed is put into vacuum electric furnace.Before heating, must guarantee that body of heater cooling system is working properly, vacuum system is working properly;
5, the temperature rise period: carry out rapid heating (50 ℃/below min) under the condition that can allow at equipment from room temperature to 1400 ℃; Within the scope of 1400 ℃-1650 ℃, need to control heat-up rate (being less than 5 ℃/min) and keep vacuum tightness (0.01Pa is following), be beneficial to the smooth discharge of gas between powder.Then be rapidly heated to top temperature and keep for some time, if blue jade top temperature is 1750 ℃ of soaking time 30-60min, green jade top temperature is 1800 ℃, soaking time 100-120min;
6, cooling stages: after insulation finishes, cut off heating power supply, keep carrying out furnace cooling under vacuum condition in stove; When cooling temperature is reduced to 1100 ℃, constant temperature keeps 30min to eliminate due to the quick cooling internal stress producing; After finishing, insulation cools to room temperature with the furnace;
