Zircon powder can significantly improve the performance of ceramic products in the ceramic industry, mainly through the following ways:

I. Improving wear resistance and hardness

Zircon powder has high hardness and wear resistance, which can significantly enhance the wear resistance of ceramic products. For example, adding zircon powder to ceramic tiles can significantly reduce the wear at room temperature and improve the strength and heat resistance of ceramics. In addition, zircon powder can improve the hardness of ceramic glaze and enhance its scratch resistance.

II. Improving the bonding performance of the blank and glaze

Zircon powder has good chemical stability, which is not affected by the sintering atmosphere of ceramics, and can significantly improve the bonding performance of ceramics. This makes the ceramic products less prone to cracks, pores and other defects during firing, thus improving the overall quality and stability of the products.

III. Increase the surface smoothness

Zircon powder is widely used in the glaze process of ceramics, which can make the surface of ceramics smoother and more delicate, and improve the appearance quality of products. Its high refractive index (1.93-2.01) and good opacification can also make the ceramic glaze show better luster and whiteness.

IV. Improving chemical resistance and high temperature resistance

The fire resistance of zircon powder is as high as 2500℃, which can keep stable in high temperature environment. In addition, its chemical stability makes it difficult to react with other substances during ceramic firing, thus improving the chemical corrosion resistance of ceramic products.

V. Optimizing the microstructure of ceramics

In the production of ceramics, zircon powder can be used as mineralizer, which can promote the sintering of ceramic matrix and optimize the microstructure of ceramics, thus improving the compactness and strength of ceramics. For example, adding zircon powder to alumina-based ceramic cores can significantly improve their room temperature and high temperature properties.

VI. Enhance UV resistance and aging resistance.

In some ceramic products, adding zircon powder can improve the anti-ultraviolet and anti-aging properties of products and prolong their service life.

To sum up, zircon powder has significantly improved the overall performance of ceramic products by improving wear resistance, hardness, surface smoothness, chemical resistance and high temperature resistance, and is widely used in building ceramics, sanitary ceramics, daily-use ceramics and special ceramics.
