Applications of zirconium silicate powder

(1) As an additive in ceramic glazes, zirconium silicate, within a certain particle size range, exhibits improved whiteness, rezistenţă, rezistenta la uzura, hydrolysis resistance, and corrosion resistance with decreasing particle size, enhanced self-cleaning ability, and reduced dosage.

(2) Due to its strong hydrolysis resistance, zirconium silicate powder can serve as a carrier for nano-functional powders in aquatic environments.

(3) Due to its strong oxidation resistance, zirconium silicate can be used as a surface coating agent for functional powders. De exemplu, the red glaze of Chinese red ceramics uses a nano-zirconium silicate coating agent, resulting in a bright and vibrant red color that does not fade.

(4) Due to its high strength and good wear resistance, nano-zirconium silicate powder is a high-quality grinding media and raw material for engineering ceramics.

Zirconium silicate powder is used in the ceramics industry.

Zirconium silicate has a wide range of applications and is used in large quantities in the processing and production of ceramic glazes. Due to its excellent chemical stability, zirconium silicate is not affected by the firing atmosphere during ceramic production, significantly improving the bonding performance of ceramic glazes and increasing the hardness of the glaze surface.
