Description
White Tabular Alumina is a high-quality, synthetic refractory material that is widely used in various industries for its excellent mechanical, thermal, and chemical properties. It is produced by sintering high-purity alumina powder at high temperatures, resulting in a unique crystal structure that provides exceptional properties.
White Tabular Alumina has a minimum purity of 99.5% and a white, ultra-fine powder appearance. It has a high melting point of 2040°C (3704°F), low thermal expansion coefficient of 5.6 x 10^-6 /°C, and a high compressive strength of 2600 MPa. These characteristics make it an ideal material for applications that require high-temperature resistance, abrasion resistance, dimensional stability, and chemical resistance.

White Tabular Alumina is a high-purity form of aluminum oxide that is produced by sintering alumina powder at a high temperature. It has a unique hexagonal crystal structure that makes it an excellent material for use in high-temperature applications, such as refractory linings in furnaces and kilns. Its high mechanical strength, excellent thermal shock resistance, and low porosity make it ideal for use in abrasive and cutting tools, grinding media, and as a filler in various composites.
