The Application of Wollastonite

The main component of wollastonite is CaSi3O9, which is fibrous and needle shaped. It has non-toxic, chemical corrosion resistance, good thermal stability and dimensional stability, glass and pearl luster, low water absorption and oil absorption value, good mechanical and electrical properties and other characteristics. It is widely used in ceramics, rubber, plastics, metallurgy, coatings, paint and building materials and other industries. With high market value, it has become a huge application market demand An important foundational non-metallic mine with broad development prospects.

The products in the wollastonite market are mainly divided into: wollastonite powder, ultra-fine wollastonite powder, needle shaped wollastonite powder, and modified wollastonite powder.

The apparent consumption structure of wollastonite is closely related to the market structure of wollastonite products. The apparent consumption structure of Chinese wollastonite is: for ceramics, accounting for approximately 47%; Used for metallurgical protective slag and welding electrodes, accounting for approximately 30%; Used for coatings, plastics, etc., accounting for about 20%; Emerging fields such as new composite materials, electronic components, and packaging materials account for relatively little, accounting for about 3%.
