Description
Technical field
The present invention relates to the synthetic field of jewel and jade, particularly a kind of lagoriolite crystalline synthetic method with jade characteristic.
Background technology
Jewel and jade are regarded as the thing that luckiness is avoided evil spirits from ancient times, be noblely, pure buy, elegant, rich and honour, peaceful and comfortable, happy symbol, compare with gold and silver, jewel and jade have the effect of explaining will and value preserving concurrently except that slightly better attractive in appearance.Because the storage capacity rareness of natural gemstone and jade, can not satisfy social needs, along with the reach of science, people are by synthetic multiple jewel of artificial means and jade, make jewel and jade be transformed into a kind of renewable resources, to satisfy human social demand by rare mineral wealth.The synthetic jewel has experienced nearly 100 years history, and nowadays common synthetic gem has synthetic ruby on the jewelry market, synthetic sapphire, synthetic starlight ruby, synthetic emerald, synthetic spinel, titania and synthetic opal etc.Synthesis of cubic zirconium white, yttrium pyralspite, GGG (GGG) and strontium titanate have the water caltrop structure and the optical characteristics of diamond, become the imitation of diamond.The method of synthetic gem mainly contains 4 kinds of flame melt method, scorification, hydrothermal growth process and fusing assistant flux growth methods.
The synthetic jade is mainly around emerald synthetic, quartzy synthetic, agate synthetic and quartzy synthetic.Wherein quartzy synthetic, agate synthetic and quartzy synthetic are succeedd and are realized commodity production, because emerald has special construction and chemical property, synthetic difficulty is big, though AM General company has synthesized successfully, but be subjected to the restriction of cost, the commercialization production in enormous quantities of still being unrealized so far.
Though, synthetic multiple hard mass and jade still are subjected to the restriction of synthetic technology in the society, and the cost of synthetic jewel and jade is also very high, current synthetic jewel and jade are used in high-grade luxury goods more, can't be widely used in human daily living article and home decoration articles for use.Therefore, the jade material of synthesizing new satisfies human daily living article and home decoration articles for use and is necessary.
Summary of the invention
The present invention provides a kind of lagoriolite crystalline synthetic method with jade characteristic.The technical process of this synthetic method is: with aluminium hydroxide and water glass is initial feed, through the NaOH catalyzed reaction, generates single lagoriolite (NaAlSiO
4), the single lagoriolite that obtains again with inorganic acid solution and sodium silicate solution hybrid reaction, obtain two lagoriolite (NaAlSi of homogeneous
2O
6) pressed powder, become block through high temperature polymerization at last, the two lagoriolite crystal that obtain having the jade characteristic.Synthesis process flow diagram such as accompanying drawing 1, synthetic particular content comprises:
1. single lagoriolite (NaAlSiO
4) pressed powder is synthetic
In reactor, at first add aluminium-hydroxide powder, sodium silicate aqueous solution and catalyzer sodium hydroxide, aluminium hydroxide and water glass mol ratio are 0.5～1.0; The mol ratio of sodium hydroxide and aluminium hydroxide is 0.2～2.0, and 10～120 ℃ of temperature of reaction are kept reaction 2～48 hours, and reaction produces single lagoriolite solid precipitation, after filtration single lagoriolite solid precipitation, chemical equation is expressed as:
2. two lagoriolite NaAlSi
2O
6Pressed powder is synthetic
Get single water glass sodium solid dispersed in water, add inorganic acid solution and regulate acidity-basicity ph=3～8, add sodium silicate solution again with single lagoriolite equimolar amount, keep 10～100 ℃, reacted 12～72 hours, behind the stopped reaction, filter and obtain two lagoriolite pressed powders, chemical equation is expressed as:
NaAlSiO
4+Na
2SiO
3+2H
+→NaAlSi
2O
6+3Na

3. two lagoriolite high temperature polymerizations reaction
The two lagoriolite solids that obtain through swager moulded section, are transferred in the high-temperature reactor polymerization reaction take place under 950～1150 ℃ of conditions, reaction times 4-48h, the compound polycrystal of two lagoriolites that obtains having the jade characteristic.Through chiseling and carving processing, just obtain two lagoriolite crystal jade devices again.
The present invention has the following advantages:
(1) single lagoriolite and two single lagoriolites are synthetic is to carry out at normal pressure and cold condition, and conversion unit is simple, and is simple to operate, and energy consumption is little;
(2) raw material that reacts as high temperature polymerization with one matter composition (two single lagoriolites) and a small amount of additive, this reaction only relates to the change of molecular conformation, do not relate to the change of the chemical bond between the atom, thereby obtain the jade material of high-crystallinity, degree of crystallinity can reach 90-98%;
(3) the synthetic lagoriolite crystal with jade characteristic of the inventive method has vitreous luster, and is glittering and translucent, the transparency height, and hardness height, intensity are big, have the higher elasticity function.
(4) synthetic gems can further be chiseled and carved processing, makes high-grade vessel, artwork and high-grade house ornament.
(5) adopt cost of material low, simple to operate, make the cost of this synthetic gems lower, can satisfy the cost requirement of production daily life with device and house ornament.
