Calcinated Alumina Powder

Calcinated alumina powder is a high-purity alumina powder material produced from aluminum hydroxide through a high-temperature calcination process. During calcination, moisture and impurities in the raw material are removed, forming a stable α-alumina crystalline phase structure. This results in a product with high hardness, high melting point, high temperature resistance, good chemical stability, and excellent electrical insulation properties.

Calcinated alumina powder is widely used in ceramic materials, refractory materials, polishing materials, catalyst carriers, electronic ceramics, thermally conductive fillers, coating materials, and other industries, making it one of the important basic industrial materials.

Calcined alumina powder features high purity, stable alpha crystal structure, high hardness, excellent wear resistance, and outstanding thermal stability. After high temperature calcination, the alumina powder forms a stable α-Al₂O₃ phase, which provides excellent high temperature resistance, chemical stability, and electrical insulation properties. With uniform particle size distribution, low impurity content, and stable sintering performance, calcined alumina powder is widely used in ceramics, refractory materials, polishing materials, catalyst carriers, and thermal conductive materials. It is an important industrial alumina material for high temperature and high performance applications.

Q: What is the difference between calcined alumina and activated alumina?

A: Calcined alumina and activated alumina are two different alumina products used for different purposes.

Calcined alumina is mainly used in industries such as ceramics, refractory materials, polishing materials, and thermal conductive materials, while activated alumina is a porous adsorbent material mainly used in drying, adsorption, water treatment, and catalyst support.

In short:

Calcined alumina: Powder material, used in material manufacturing.

Activated alumina: Porous adsorbent, used for adsorption and drying.

Q:Can you customize calcined alumina powder?

A:We can provide customized products based on customer applications, such as:

different particle sizes
