Zircon sand has been widely used in many high temperature processes because of its high melting point (2550℃-2750℃) and excellent high temperature resistance. The following are the most widely used fields of zircon sand in high temperature process:

I. Refractory materials

Zirconium sand is an important raw material for manufacturing refractory materials, which is widely used to produce zircon bricks, zirconia corundum bricks, refractory castables and other products. These refractories have high melting temperature, good corrosion resistance and thermal shock resistance, and are suitable for glass kilns, cement kilns, ceramic kilns and high-temperature kilns in metallurgical industry. For example:

Glass kiln: Refractory bricks made of zircon sand can withstand the high temperature during glass melting and reduce the pollution to glass liquid.

Metallurgical lining: Zirconium-based refractories can withstand extreme temperature and chemical erosion in high-temperature lining of steel, nonferrous metallurgy and other industries.

II. Precision casting

Zircon sand is an ideal molding sand material in the field of precision casting, especially suitable for manufacturing high-precision and high-strength metal parts. Its high refractoriness and low thermal expansion coefficient ensure the dimensional accuracy and surface quality of castings. For example:

Aerospace parts: Zirconium sand is needed as molding sand for the casting of high-precision parts such as turbine blades.

Automobile engine parts: zircon sand with high refractoriness can withstand the impact of high temperature metal liquid and ensure the quality of castings.

III. Ceramic industry

Zircon sand, as an additive for glaze and green body in ceramic production, can significantly improve the mechanical strength, wear resistance and thermal shock resistance of ceramic products. For example:

High-temperature ceramics: used to manufacture high-performance ceramic materials such as electronic ceramics and structural ceramics.

Ceramic glaze: improve the gloss and wear resistance of ceramic products.

IV. Glass industry

In the process of glass manufacturing, zircon sand can be used to produce refractory materials for glass furnaces, such as zircon bricks and ramming materials. These materials can withstand the high temperature of glass melting and reduce the pollution of glass melt.

V. Nuclear industry

Zirconium sand is used as shielding material for nuclear reactors and cladding material for fuel rods because of its excellent radiation resistance and high temperature stability. In the nuclear industry, high-purity zircon sand can improve the efficiency and safety of nuclear reactors.

VI. Chemical equipment

Zirconium sand can be used to manufacture high-temperature pipes, high-temperature valves and other chemical equipment parts, which need to be stable in high-temperature and corrosive environment.

VII. Other high-temperature processes

High-temperature furnace tube and furnace cover: high-temperature equipment used in steel, chemical and other industries.

High temperature ceramic coating: used to improve the high temperature resistance and corrosion resistance of materials.

To sum up, the high refractoriness of zircon sand makes it play an irreplaceable role in high temperature processes such as refractories, precision casting, ceramics, glass and nuclear industry.
