65-66% Zirconium silicate powder
Introduction of 65-66% Zirconium silicate powder
65-66% Zirconium silicate (ZrSi04) is made from High-grade natural zircon sand by ultrafine grinding, iron & titanium removal, and surface modification processes. Zirconium silicate powder is always used as a high-quality ceramic glaze opacifier, whitening agent, anti-seepage agent, and stabilizer.
Zirconium silicate powder has good chemical stability, is not affected by the firing atmosphere of ceramics, and can significantly improve the bonding performance of ceramic bodies and glazes, and increase the hardness of ceramic glaze surfaces. It is widely used in the production of ceramic tile, sanitary ware ceramics, ceramic craft, emulsified glass, etc.
65-66% Zirconium silicate powder Features:
- High zirconium oxide purity. Low Ferro, low titanium oxide.
- High whiteness.
- Good thermal performance and high refractoriness.
- Extremely wear-resistant.
- Low thermal expansion and chemical stability.
