Application
1. The ceramic industry
The sufficient wollastonite is added to ceramic material, the baking temperature can ber decreased, and baking duration greatly shortened to a low temperature bake, so as to save fuel and producing costs. In the meantime,improve the cracks and streaks on the products, proventing of cracking, denting, breakage and glaze defects.

2. The paint and coating industry
Used as a filler agent in paint, so super quality, brightly paint could be
achieved.

3. The rubber and plastic industry
Used for the thermo-impact strength, improve stiffness and dimensional stability.

4. In metallurgy industry
As a key ingredient in flux and continues casting, protect slag in casting silicon-steel, electrode coating.
