Abstract

The invention discloses a method for synthesizing a sodium alumino silicate crystal with jade property. The method comprises the following steps of: generating monomer sodium alumino silicate (NaAlSiO4) by aluminum hydroxide and sodium silicate serving as initial raw materials through a NaOH catalytic reaction; allowing the prepared monomer sodium alumino silicate to mix and react with inorganic acid and sodium silicate solution to obtain sodium alumino disilicate (NaAlSi2O6) solid powder; and preparing the sodium alumino silicate polycrystal with jade property through a high-temperature polymerization reaction. The method has the advantages that: 1, the method adopts low-price raw materials, synthesis of the monomer sodium alumino silicate and the sodium alumino disilicate is performed under normal pressure and at a low temperature, and simple reacting equipment, simple operation and small energy consumption ensure lower cost for synthesizing jade; and 2, the jade material synthesized by the method has glass luster, glitter, high transparency, high hardness and high strength, has higher elastic function, and can be further carved into high-grade vessels and craftworks.

Description

technical field [0001] The invention relates to the field of synthesis of gemstones and jade, in particular to a method for synthesizing sodium aluminum silicate crystals with characteristics of jade. Background technique [0002] Gems and jade have been regarded as auspicious and evil objects since ancient times. They are symbols of nobility, purity, elegance, wealth, peace and happiness. Compared with gold and silver, gems and jade are not only slightly better in appearance, but also expressive. The role of mind and value preservation. Due to the scarcity of natural gems and jade storage, it cannot meet the needs of society. With the development of science, people synthesize a variety of gems and jade artificially, so that gems and jade are transformed from rare mineral resources into a renewable resource to meet the needs of society. human social needs. Synthetic gemstones have a history of nearly 100 years. The common synthetic gemstones in the jewelry market today inc...
