Zircon powder is an important industrial material with many superior properties, so it is widely used in many fields. The following are the main uses of zircon powder:

I. Investment casting (precision casting) field

Zircon powder is mainly used in investment casting to make mold coatings and ceramic cores. Its high purity and low impurity content 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 the ceramic industry:

Main material: used for manufacturing high-performance ceramics, improving the strength, wear resistance and high temperature resistance of ceramics.

Glazing: As an opacifier, it increases the wear resistance and surface smoothness of ceramics, and at the same time improves the hardness of ceramic glaze.

Bonding performance between blank and glaze: Because of its good chemical stability, zircon powder is not affected by the atmosphere during the firing process of ceramics, which can significantly improve the bonding performance between blank and glaze of ceramics.

III. Glass industry

Zircon powder also has important applications in glass manufacturing:

Emulsified glass: used to make color picture tubes in TV industry and emulsified glass in glass industry.

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

IV. Refractory materials

Because of its high melting point (2500℃), zircon powder is of great value in the field of refractories:

Refractory bricks: used to produce zirconium refractory materials, such as zirconia corundum bricks.

Castables and paint spraying: Zirconium ramming materials, castables and paint spraying used in glass furnaces.

V. Chemical industry

Zircon powder is widely used in chemical industry:

Cosmetics: used as raw materials to make cosmetics.

Food preservative: used as food preservative.

Leather making and fiber: used to make flame retardant fiber.

VI. Other applications

Coating industry: as an additive, 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: It is an ideal filler for resin, plastic and silica gel due to its wear resistance.

Brake pads and polishing materials: used to manufacture brake pads and polishing materials.

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.
