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.
