Wollastonite Powder

Ceramic Grade (for Glaze)

Features:

1) 100 mesh to 325 mesh

2) When sufficient wollastonite is added to ceramic material, the baking temperature can be decreased, and the baking duration greatly shortens to one rapid low temperature bake, thus saving fuel and reducing production costs

3) At the same time the mechanical properties are improved, cracks and streaks on the products are eliminated and quality is improved.
