TM-CA Series Calcined Alumina

Product Attribute:

Applicationt: 

calcined alumina, alpha alumina

Production Description:

Features:
This series of product has a stable performance, a good process performance, and a wide application. Its crystal size is big. It is specially used in the production of ceramic products with the methods of grouting and hot molding. It can also be used in roll forming and dry pressing. Product shrinkage is small.
Applications:
       It is widely used in a variety of high temperature resistant porcelain (spark plug, etc), wearproof porcelain (liners of mortar pump and axial piston pump, impellor, grinding media ball, etc), electronic substrate, electric vacuum tube, shaped or unshaped refractories, etc.
