Reasonable Price Refractory Grade Calcined Alumina Powder at Low Market Price

Calcined  alumina for making polishing wax is produced through the calcination (“heating”) of alumina to various temperatures.  By controlling the calcination temperatures and time, the properties of the alumina can be controlled.  Calcined alumina is therefore utilized in a variety of industrial applications including Structural ceramics, Technical ceramics, Polishing compounds for plastic, metal, and glass, Fillers for Rubber and Plastics, Friction - anti slip, Refractories, Paint & Coatings and Thermal Spray Powders.

Using high quality 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.
