Zircon powder has a wide range of industrial applications, covering casting, ceramics, refractories, chemical industry and other fields. The following are its main applications:

I. Foundry industry

Mold coating and ceramic core: zircon powder is widely used as mold coating and ceramic core in investment casting (precision casting) because of its high melting point and low expansion rate. It can ensure that the casting does not deform during high temperature pouring, and at the same time improve the surface smoothness of the casting.

Refractory filler: zircon powder is often used as refractory filler in the production of large and medium-sized steel castings, important steel castings and iron castings, which can reduce the workload of cleaning castings and obtain castings with smooth surfaces.

II. Ceramic industry

Main material and glazing: zircon powder can be used as both main material and glazing in ceramic industry. It can significantly improve the wear resistance and surface smoothness of ceramics, and at the same time improve the bonding performance of ceramics.

Ceramic glaze: Because of zircon powder's high refractive index (1.93-2.01) and chemical stability, it is widely used in the production of various building ceramics, sanitary ceramics, daily-use ceramics and handicraft ceramics.

III. Refractory materials

Refractory products: zircon powder is used to produce all kinds of refractory products, such as refractory bricks, refractory fibers and casting materials. These materials can withstand high temperature and corrosive environment, and are widely used in furnace lining in metallurgy, glass, ceramics and other industries.

High temperature furnace lining: Its high melting point (above 2500°C) and good thermal stability make it an ideal high temperature furnace lining material.

IV. Chemical industry

Opaque agent: zircon powder is a high-quality and cheap opacifier, which is widely used in the processing and production of ceramic glaze.

Other applications: zircon powder is also used in cosmetics, cement, food preservation, tanning, fiber (manufacturing flame retardant fiber) and other fields.

V. Glass industry

Glass manufacturing: zircon powder is used in glass manufacturing industry, which can improve the quality and service life of glass.

Optical glass: Its high refractive index and chemical stability make it used in optical glass and TV glass, which can stabilize the composition of glass and increase chemical resistance.

VI. Other applications

Brake pads and polishing materials: zircon powder is used in brake pads, clutch linings and polishing materials due to its wear resistance.

Flame-retardant materials: zircon powder's flame-retardant properties make it used in tanning and the production of flame-retardant fibers.

To sum up, zircon powder plays an important role in many industrial fields because of its unique physical and chemical properties, and its application scope is still expanding with the progress of technology.
