Product description:
1. This Tabular Alumina is white. It is available in a variety of particle sizes and reticulated powders. It has excellent properties in advanced refractory applications, so it is commonly used in high temperature engineering equipment, metallurgical and chemical fields, ceramics and building materials. It is a fully contracted coarse crystalline alpha alumina that has been converted to a corundum form. The flake alumina is prepared by sintering spherical intermediate calcined calcined alumina at a temperature just below the melting point of 2040 ° C of alumina. The flaky alumina balls can be crushed, classified or sieved, ground and mixed into various granule or powder particle size distributions.
2. Tabular Alumina is chemically inert and therefore resistant to most alkali and inorganic acids. It has high density, low water absorption, high hardness, high thermal conductivity, good heat resistance and mechanical impact properties. In addition, it has high heat capacity, high electrical resistance and excellent wear resistance. Tabular Alumina has good thermal shock resistance and long service life. It is completely crystalline.
