Description
Wollastonite has many excellent performances including fine insulativity, high whiteness,good dielectric property and better heat-resisting and weather-resisting performances. Wollastonite can be widely used in the fields of ceramics, chemical industry, metallurgy, papermaking, plastics, coating and other fields.
Our wollastonite have many advantages such as lower Fe content, lower LOI and higher whiteness. Our wollastonite is chosen by manpower. It is defined into two classes-Class I and Class II based on different Ca contents.
