Features:
This series of product is produced by adoption of advanced formula and strict process. It has good characteristics of fine primary crystal size, loose crystal combination, good grindability and easy sintering. It can reduce the ceramic firing temperature by 50~100 degree centigrade. It is used in the production of ceramic products by the way of roll forming, tape casing, dry pressing, isostatic pressing, hot molding, grouting, etc. It can make the ceramics dense and smooth with high mechanical strength and good insulation, which makes it an ideal choice for special ceramics manufacturing.
Applications:
It can be used in all kinds of wear-resistant ceramics, high temperature resistant porcelain, electronic substrate, shaped or unshaped refractories, etc. Its coarse powder is of good fluidity and is specially used in electric melting alpha-beta bricks.
