NATURAL LOW-FE WOLLASTONITE - NATURAL LOW-FE WOLLASTONITE
APPLICATIONS
1. The ceramic industry
when sufficient wollastonite is added to ceramic material, the baking temperature can be decreased, and the baking duration greatly shortened to one rapid low temperature bake, thus saving fuel and reducing production costs. At the same time the mechanical properties are improved cracks and streaks on the products are eliminated and quality raised.
2.The paint and coating industry
When wollastonite is u...[more]
