Zircon powder is widely used in many fields because of its excellent physical and chemical properties. The following are its main application fields:

I. Investment casting (precision casting) field

Zircon powder is mainly used in investment casting to make mold coatings and ceramic cores. Its high purity, low impurity content and good high temperature resistance can effectively prevent the penetration and adhesion of molten metal, thus improving the quality and surface smoothness of castings. In addition, the fine particle characteristics of zircon powder can form a uniform and sealed coating, which makes the surface of castings smooth and delicate, and is widely used in high-end industries such as aviation and medical devices.

II. Ceramic industry

Zircon powder has many uses in ceramic production:

As the main material, it is used to manufacture high-performance ceramics and improve the strength, wear resistance and high temperature resistance of ceramics.

Used for glazing ceramics to increase the wear resistance and surface smoothness of ceramics.

Because of its high refractive index (1.93-2.01) and chemical stability, zircon powder is widely used in the production of building ceramics, sanitary ceramics, daily-use ceramics and handicraft ceramics.

Zircon powder can also significantly improve the bonding property of ceramic body and glaze, and improve the hardness of ceramic glaze.

III. Glass industry

Zircon powder also has important applications in glass manufacturing:

Used for making color picture tubes in TV industry and emulsified glass in glass industry.

In optical glass and TV glass, zircon powder can stabilize the composition of glass, increase chemical resistance and resist harmful X-rays.

IV. Refractory materials

Zircon powder's high melting point (2500℃) makes it of great value in the field of refractories;

Zirconium ramming material, castable and paint spraying used for producing refractory bricks and glass furnaces.

In the high temperature environment, zircon powder can maintain stability and prolong the service life of refractories.

V. Chemical industry

Zircon powder is widely used in chemical industry:

Used to make cosmetics, food preservatives, tanning materials and flame retardant fibers.

As an opacifier, it is widely used in the production of ceramic frits.

VI. Other applications

Coating industry: zircon powder, as a coating additive, can improve the weatherability and adhesion of coatings.

Electronic industry: Because of its excellent insulation performance, zircon powder is used in the production of electronic components.

Resin and plastic filler: zircon powder's wear resistance makes it an ideal filler for resin, plastic and silica gel.

Brake pads and polishing materials: zircon powder is used to manufacture brake pads and polishing materials due to its wear resistance.

To sum up, zircon powder, with its high purity, high melting point, high refractive index and good chemical stability, has a wide application prospect in investment casting, ceramics, glass, refractories and chemical industry. With the continuous progress of technology, its application field is still expanding.
