Artificial crystal _ what is artificial crystal


Artificial crystal is high lead glass, or called lead crystal, be in namely common glass (component is silica) adding 24% of the lead oxide, will get brightness and transparency and natural crystal similar artificial crystal.

Artificial crystal is raw material quartz sand through series of working procedures abstraction, and fine cutting technology and no flawless burnish kung fu is made and become, artificial crystal pure and transparent, to make up for the lack of natural crystal.



Artificial crystal add into metal elements such as lead can enhance the light shot down, more show crystal nobility. Due to the artificial crystal process multifarious, technology superb, some even more than the price of natural crystal and expensive.

Molecular formula: alpha SiO2

Properties: artificial methods growth alpha quartz crystal. α quartz under high pressure can soluble in alkaline solution. Crystal structure is complete, including twin, hole, inclusion less. Use its solubility with temperature to reduce and decreases, can from hydrogen sodium hydride or sodium carbonate solution grow a α quartz crystal. Synthesis pressure 16.5 MPa, the temperature is 400 ℃. In the (001) basal growth rate 1.27 u m/day. Mainly used in electronic industry, ultrasonic generator, optical instrument and analysis instrument.

Features: the content of lead oxide international standard is 24%, then the man-made crystal chemistry performance is best, and compared with common glass, mainly is more than major, feel is heavy; Refractive index is large, can the transmission spectrum of the colorful ten color; High hardness, wear.

Purpose: lead oxide containing 24% of lead glass through the refining, impurities, hand blown, grinding and polishing, fine carving, can be made into high-grade quality lead glass art, light rays pass through the carved facet can reflect colorful six color.

Standard: the international Glass has a strict concept, Glass: namely ordinary Glass products. Crystal: both lead glass, or call Crystal, lead oxide content up to 24%. Therefore, lead oxide containing 24% high quality high lead glass guarantee.
