The common ones are α-Al2O3 and γ-Al2O3. Corundum in nature is α-Al2O3, hexagonal close-packed crystals. α-Al2O3 has a melting point of 2015±15°C, a density of 3.965g/cm3, and a hardness of 8.8. It is insoluble in water, acid or alkali. γ-Al2O3 is a cubic close-packed crystal, insoluble in water, but soluble in acid and alkali, and
The chemical formula of alumina powder is Al2O3, and the molecular weight is 101.96. The main component of alumina, white powder. There are different crystal forms, the common ones are α-Al2O3 and γ-Al2O3. Corundum in nature is α-Al2O3, hexagonal close-packed crystals. α-Al2O3 has a melting point of 2015±15°C, a density of 3.965g/cm3, and a hardness
Alumina powder (Al2O3) is a white amorphous powder, belonging to inorganic oxide, insoluble in water, soluble in strong alkalis and strong acids, melting point 2054°C, boiling point 2980°C, with high purity and whiteness High, high specificity, good thermal stability, uniform particle size distribution and good fluidity; alumina has many isomers, and the alumina powder prepared
The effect of alumina ball on water treatment is better. Everyone knows this, but many people don’t know when the alumina ball will be replaced. Some people even replace the alumina ball before it is effective. This not only wastes financial resources, but also wastes resources. Then when should the alumina balls be replaced? Let
It is generally used for grinding media, which has the characteristics of low price and low wear. Its role and function are similar to zirconia grinding balls, so what is the difference between these two different types of products? 1. Alumina grinding ball. It refers to the use of bauxite, roller powder, alumina, and high-temperature
Alumina lining bricks products have the characteristics of high hardness, high density, low abrasion, good regularity, and corrosion resistance. Alumina bricks are used for wear-resistant linings of ball mills.
