  • Zirconium Silicate

    Zirconium Silicate

    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.

    1

    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.
