What Is The Difference Between Active Aluminum Oxide Powder And High Temperature Aluminum Oxide Powder

High temperature aluminum oxide powder is made of industrial aluminum hydroxide, bauxite, molecular sieve and grinding ball after long-term high-temperature calcination in tunnel kiln. In the smelting process, the carbon in anthracite reduces the impurities such as silicon oxide (SiO2), iron oxide and titanium oxide in bauxite into metals. These metals are combined to form ferroalloys. Because their density is higher than that of corundum melt, they settle to the furnace bottom and separate from corundum melt. High temperature aluminum oxide powder has strong crushing resistance, oxidation resistance, corrosion resistance and good chemical stability. It is an abrasive with a wide range of uses.
Active aluminum oxide powder is an abrasive made of industrial aluminum hydroxide powder by heating, melting and recrystallization in an electric arc furnace. Impurities in raw materials are not excluded in the smelting process. Therefore, the quality of activated alumina is closely related to the purity of raw materials. The content of A12O3 in activated alumina should be more than 99.5%, and its hardness is higher than that of high-temperature aluminum oxide powder, but it is brittle.
It has good cutting, anti-oxidation and gas corrosion properties, and has good insulation. It is mainly used for fine grinding and fine grinding of quenched steel and alloy steel, grinding threads and gears, etc. active aluminum oxide powder can also be used for precision casting and high-grade refractory materials.
