Description
Zirconium silicate, with the chemical formula ZrSiO4, is a naturally occurring silicate mineral known for its gemstone quality crystals called cubic zircons, which resemble diamond gemstones. It is colorless in its pure form, but the presence of impurities can result in various colors such as red, brown, yellow, or green. The red gem-quality zircon is sometimes referred to as jacinth, while those with other colors are called jargoons. There is also a naturally occurring colorless variety, and colorless varieties can be produced through heat treatment. Zirconium silicate exhibits a tetragonal crystal structure, has a density of 4.56 g/cm3, and a hardness of 7.5 Mohs. It dissociates to ZrO2 and SiO2 above 1,540°C and melts at 2,550°C. It is insoluble in water, acids, aqua regia, and alkalies, making it inert in most chemicals.
Uses
Zirconium silicate is used in various applications across different industries due to its unique properties:
Used in Gemstone Industry:
Zirconium silicate is used as a gemstone for its resemblance to diamond gemstones. The color of the gemstone depends on the presence of small amounts of other metals, and it can be red, brown, yellow, or green. The colorless varieties, either natural or treated, are sometimes called Matura diamonds.
Used in Glass and Ceramic Industry:
Zirconium silicate is used as an additive to glass, in ceramic tiles, in ultrafiltration membranes, and as a dental abrasive. It is also used in the production of some ceramics, enamels, and ceramic glazes, where it serves as an opacifier.
Used in Refractory Materials Industry:
Zirconium silicate is used for manufacturing refractory materials that require resistance to corrosion by alkali materials.
Used in Cement Industry:
Zirconium silicate can be present in some cements to enhance their properties.
Used in Milling and Grinding Industry:
Zirconium silicate is used as beads for milling and grinding applications.
Used in Thin Film Industry:
Thin films of zirconium silicate and hafnium silicate are produced by chemical vapor deposition, which have potential applications in various industries.
Used in Semiconductor Industry:
Zirconium silicate is a potential alternative gate dielectric to silica in the semiconductor industry.
Used in Cosmetics Industry:
In Europe, zirconium silicate is used in cosmetic creams and powders to provide specific benefits to the skin.
Preparation
Zirconium silicate occurs in nature as mineral zircon. Ore is mined from natural deposits and concentrated by various techniques (See Zirconium, Recovery). It is separated from sand by electrostatic and electromagnetic methods. Also, the compound can be made by fusion of SiO2 and ZrO2 in an arc furnace, or by reacting a zirconium salt with sodium silicate in aqueous solution.
Check Digit Verification of cas no
The CAS Registry Mumber 10101-52-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,0 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 10101-52:
(7*1)+(6*0)+(5*1)+(4*0)+(3*1)+(2*5)+(1*2)=27
27 % 10 = 7
So 10101-52-7 is a valid CAS Registry Number.
