High Quality Factory Direct ZrSiO4 Powder Zirconium Silicate for Ceramics and Glass CAS 10101-52-7 Product Description Product Description Of Zirconium Silicate Zirconium silicate is a non-toxic, odorless white or off-white powder. The raw material is natural high-purity zircon sand concentrate, which is then processed through superfine grinding, iron removal, titanium processing, and surface modification treatment. Zirconium silicate has a high refractive index of 1.93-2.01 and stable chemical performance. It is a high quality and low price opacifier for opacification. It is widely used in the production of various building ceramics, sanitary ceramics, daily ceramics and first-class handicraft ceramics. Zirconium silicate has been widely used in ceramic production because of its good chemical stability, so it is not affected by the burning atmosphere of ceramic, and can improve the binding performance of ceramic glaze significantly and improve the hardness of ceramic glaze. Zirconium silicate has been further applied in the production of color picture tube, emulsified glass and enamel glaze in the glass industry. Product Feature of Zirconium Silicate zirconium silicate has high refractive index, good chemical stability and high temperature resistance Specification 1.Zirconium Silicate Physical properties Specific Gravity 4.69 Melting Point 2500°C Refractive Index 1.97 Mohs Hardness 7.5 Thermal Expansion Coefficient 4.2*10-6 Apprearance White or off white powder 2.Zirconium Silicate Chemical properties Item RS65 RS64.5 RS63.5 ZrO2+HfO2 65.0 min 64.5 min 63.5 min Fe2O2 0. 06 max 0. 08 max 0. 12 max Ti02 0.10 max 0.12 max 0.18 max 3.Zirconium Silicate Product standard Type Average mesh Application RS-1.0 D50≤1.0um High-grade sanitary porcelain High-grade daily-use porcelain High-grade crystal brick RS-1.2 D50≤1.2um RS-1.5 D50≤1.5um Middle and low class sanitation porcelain,external and internal brick, archaized brick, engobe, body, etc. RS-2.0 D50≤2.0um Product Application Product Application of Zirconium Silicate 1.Building ceramics, sanitary ceramics, daily-use ceramics, special ceramics, etc.(High refractive index 1.93-2.01,Chemical stability,It is an excellent and inexpensive opacifying agent,It is an excellent and inexpensive opacifying agent,In the processing and production of ceramic glaze, the scope of use is wide and the amount of use is large. 2.Refractory materials and products, glass kiln zirconium ramming material, castable, spray coating, etc. (zirconium silicate melting point is very high :2500ºC 3.TV industry color kinescope, glass industry emulsified glass, enamel glaze production 4.Plastics industry: used as fillers requiring stability, heat resistance and chemical erosion resistance Our Advantages Rongsheng Refractory has professional sales and after-sale service team who provide customers all-around service about product application, construction installation and operation technology training etc. Packaging & Shipping Every possible precaution is taken to ensure our products in prime condition when reach customers around the world.
