What are the characteristics and uses of activated alpha alumina powder

The main component of alumina powder, its quality determines the quality of corundum abrasive to a great extent. Not only that, high-temperature calcined alumina powder has a wide range of uses. Alumina powder has good sintering performance, high conversion rate, and low sodium content. . The quality of the product is reliable, with high melting point, good thermal stability, high hardness, good wear resistance, high mechanical strength, good electrical insulation, and corrosion resistance; the following will introduce the characteristics and uses of calcined activated α alumina powder.

Features: The new activated alumina powder production line uses high-quality imported alumina as raw material, adopts German low-temperature special-phase technology, and adds special additives for modification treatment, low-temperature phase inversion calcination into activated alpha alumina powder, and advanced grinding Technology and process, produced activated alpha alumina micropowder. The original grain size reaches 0.5-2um.

Uses: With high activity, large fineness and good particle shape, it is an ideal raw material for producing various unshaped refractory materials. Because of its high activity and fineness, it has the effect of lowering the firing temperature and improving high-temperature performance indicators especially for qualitative products.

The application of alpha alumina in new alumina ceramics

Although there are many varieties of new ceramic materials, they can be roughly divided into three categories according to their functions and uses functional ceramics (also known as electronic ceramics), structural ceramics (also known as engineering ceramics), and biological ceramics. It can be divided into oxide ceramics, nitride ceramics, boride ceramics, carbide ceramics, and cermets

What are the crystal forms of alumina powder

The crystal forms of Al2O3 are: α, γ, η, δ, θ, κ, χ and so on. When the external conditions change, the crystal form will change. In the Al2O3 variant, since the oxygen in α-Al2O3 (density 3.99g/cm3) is the most compactly packed, only α-Al2O3 (corundum) is stable, and other crystal forms are unstable. Transformed into
