Calcined Alumina Powder 
High temperature calcined alpha alumina powder is produced by aluminum hydroxide powder or industrial alumina powder as raw material, with 1450 ºC high temperature tunnel kiln calcining process, adding special additives reduce the impurity content, improve the alpha conversion rate, control the crystal shape, particle calcined under enough heat preservation time, and the micro powder is the use of high alumina ball mill grinding classification.

Features: high purity, high whiteness,  good thermal stability, uniform particle size distribution and  good liquidity .

Application: widely used in ceramics, electrical porcelain, refractories, spark plugs, brake pads, high insulation, high purity refractory fiber, high-grade castable, grinding polishing, artificial stone, etc.
