Chinese name of zirconium silicateEnglish name of Zirconium SilicateEnglish alias Silicic acid, zirconium (4 +) salt (1:1); ZIRCONIUM SILICATE, 99%;CAS NO. 10101-52-7 EINECS 233-252-7Formula ZRSIO4Zirconium silicate Zr (SiO4)Of the theory as: ZrO2: 67.1%; SiO2: 32.9%.High refractive index of 1.93-2.01, chemical stability, is a high-quality, inexpensive emulsifying agent, is widely used in the production of a variety of building ceramics, sanitary ceramics, porcelain and ceramics, an arts and crafts ceramics, etc., in the ceramic the processing of the glaze, using a wide range and volume of applications. The reason why zirconium silicate can be widely used in ceramic production, and also because of its good chemical stability, and thus not subject to the ceramic firing atmosphere, and can significantly improve the ceramic glaze, combine performance, increase the hardness of ceramic glazed. Zirconium silicate is also the color picture tube of the television industry, emulsification of the glass industry, glass, enamel glaze production of further applications. The high melting point of zirconium silicate: 2500 degrees Celsius, so zirconium refractories, glass furnace ramming mixes, castables spraying compound has also been widely used.Opacification of sexual segregation and other properties are superior to high-performance zirconium silicate with whitening and stable conditions, dispersed in zirconium silicate powder, particle morphology, particle size range, medium performance, and brick or glazed applications conventional zirconium silicate.The whitening effect of the zirconium silicate formation of baddeleyite, because in the firing of the ceramic, thus the formation of scattering of incident light waves, the scattering is commonly known as the large particle scattering or Mie scattering (MieScattering). Combined with theoretical calculations and powder production, the d50 value of the high-performance zirconium silicate is controlled at below 1.4um, d90 controlled at below 4.0um (Japan laser particle analysis to measure the value date), will produce the best Opaque whitening effect. Whitening effect of the zirconium silicate, the concentration of particle size range is very important, the narrow distribution of particles required in the grinding process of the zirconium silicate as possible.
