calcined activated alumina powder

Calcined alumina is produced by high quality and high purity raw material in the rotary furnace at reasonable temperature. It has characteristic of high conversion rate, stable crystallization and low impurity content, excellent performance of high mechanical strength, stable shrinkage rate, good electrical insulation, high wear resistance and outstanding corrosion resistance.
