Refractory Calcined Alumina

The following is a detailed introduction to the application and characteristics of alumina powder in refractory materials.

One. Application of calcined alumina powder in refractory materials

1:Hearth bricks, linings and refractory patches

Calcined alumina powder is also widely used in ceramic materials, especially in the field of refractory materials. Ceramics made using calcined alumina powder have good corrosion resistance and high temperature resistance, and are often used in the manufacture of refractory materials such as furnace bricks, furnace linings and refractory patches.

2. Casting materials

Calcined alumina powder is also used in casting materials. It can be used to make sand molds and binders for cast iron, steel and aluminum alloys, etc., to improve the quality and extend the service life of castings.

3. Environmentally friendly materials

Calcined alumina powder can also be used as an environmentally friendly material, such as lining paint for exhaust pipes and high-temperature cleaners. Because of its low pollution, non-toxic and odorless, it is a new field of environmentally friendly materials. It is also widely used in electrical dust removal materials and degradation materials that capture pollutants.

Two:Characteristics of calcined alumina powder refractory materials

1.High temperature resistance

The melting point of calcined alumina powder is as high as 2072°C, and refractory materials containing alumina have extremely high melting points and can maintain stable performance at high temperatures.

2. Corrosion resistance

Calcined alumina powder has high chemical stability and can withstand corrosion from various acids, alkalis, salts, etc., especially at high temperatures.

3. High insulation

Made from refined calcined aluminum oxide powder, it has high insulation properties and has good application prospects in electrical insulation materials.

4. High hardness

Calcined alumina powder has high hardness, strong low-pressure strength and good wear resistance, so it is widely used in refractory materials.

In summary, calcined alumina powder, as a high-performance material, has broad application prospects in the field of refractory materials. Its good high-temperature stability, corrosion resistance, high insulation and high hardness make it an indispensable and important component in the field of material manufacturing.
