产品介绍
Tabular Alumina is made by adopting the top quality industrial alumina as starting material, without any additives, fast sintered at super-high temperature(>1900ºC) The product has close packing structure of corundum grain size in th range from 1-2um to 100-200um with cross bonding and homogenized distribution, resulting in maxinum packing density. It is characterized by high refractoriness, low alkali, high bulk density, high strength, high purity and complete crystal tabularization. It has been widely used in metallurgy (slide gate, nozzle, etc), ceramics, chemical and glass industries.
