Calcined Alumina Powder

 

Our alumina material is widely accepted by customer home and abroad. It is mainly used in ceramic, refractories, glazing, e. T. C.

The calcined alumina of our company is produced by the general international law of Bayer, boron free rotary kiln calcined, in addition to sodium washed by water, greatly improving the product quality, purity and stability, and the bulk density of ceramic products, mohs hardness and ability to withstand voltage, etc.

The specification of various code is shown as belows:
