Calcined alumina is made of high-quality raw materials and calcined at high temperature. It has the advantages of high conversion rate, stable crystal shape and low impurity content. Its products have high mechanical strength, stable shrinkage rate, good electrical insulation performance, excellent wear resistance, corrosion resistance and high temperature resistance.
Using high raw materials, calcined alumina is being produced in the rotary kiln on the reasonable temperature, with the characteristic of high conversion rate, stable crystallization and low impurity content.
Its products have excellent performance of high mechanical strength, stable shrinkage rate, good electrical insulation, high wear resistance, and outstanding corrosion resistance.
