Wollastonite A-3
Wollastonite
Introduction:
Wollastonite belongs to a chain of metasilicates, is a fibrous, needle-like. Because of its special crystal morphology crystal structure determines its properties, wollastonite has good insulation, and has high whiteness, good dielectric properties and high heat and weather resistance. Wollastonite is widely used in ceramics, chemical industry, metallurgy, paper making, plastics, coatings and other fields.

Applications:
The application of wollastonite in ceramic industry is mainly used for blanks and glazes.
In the application of body, Chinese ceramic workers processed the low content of B-grade wollastonite into 200 mesh powder, which is used in the blank of wall and floor tiles to enhance the strength of the body and save energy consumption. This is a great contribution of Chinese ceramic workers, which has been rapidly promoted. The key of wollastonite billet to achieve low temperature rapid firing is that it can produce anorthite with kaolinite at about 1000℃, and diopside with talc at 1080℃.The addition of wollastonite to billet can also improve the cracking resistance of the product.
Wollastonite used in glaze requires high purity and small particle size. Wollastonite can reduce or eliminate pinholes in glaze, improve wear resistance of glaze, improve transparency and gloss of glaze layer, and use wollastonite can also produce calcalous matt glaze, the effect is very ideal. Adding a certain amount of wollastonite to glaze can also reduce the smoking phenomenon of calcium glaze.
