AA white crystalline powder, alumina is obtained by calcining aluminum hydroxide. Although there are many variations of alumina crystals, the one that is the most stable and accordingly most widely used is α-alumina. It has a high melting point, is thermally stable, and ranks next to silicon carbide, boron carbide and diamond in hardness. Moreover, it has high electric resistance and is stable against acids and alkalis. α-alumina consequently serves in broad range of application, including refractories, insulators, spark plugs, IC boards and packages, grinding and polishing materials, and heat and chemical resistant porcelains. Available are different types of alumina, each having its α-ultimate crystal size and particle size distribution and its impurities content controlled to meet the particular requirements of such applications. PT GRAINS INDONESIA provides in standard-sized and fine-sized of normal soda and low soda alumina with soda content, ultimate crystal size, shape and size distribution adjusted in production diverse customer requirements. tabular alumina is made by holding calcined alumina powder just below its 2040oC fusion temperature to recrystallize the normally flat crystals into hexagonal, elongated tablet-shaped ones up to 400 microns in size. It is possible to convert near 100% of the crystals and achieve an extremely high chemical purity. The new crystals maintain the same hardness and density and thus this grade is of interest to users that require the special properties imparted by the particle shape or size or the extra purity of material. tabular alumina is a re-crystalline sintered Alpha alumina with high density. It consists of large (50-200 µm), flat, table shaped corundum crystals. Refractory: tabular alumina is a perfect raw material for a wide array of refractory applications. It is used in the manufacture of kiln bricks, monolithic refractories, and refractory cement used to manufacture steel, aluminum, glass, and petrochemicals, and to incinerate waste. It is also used in the production of ceramics, electrical insulators, and dielectric materials. PT GRAINS INDONESIA provide high quality tabular alumina products ranging depending on the purpose of use to satisfy diverse customer requirements.
