With self-owning wollastonite mine and factory in the northeast of China, we can supply wollastonite both in lump and powder. Our wollastonite stones are selected manually and separated into different grades. We can also select wollastonite stones according to buyers' requirements for specifications and grind into powder.
Our regular powder sizes are 200mesh and 325mesh. Micropowder is also available.
The characteristics of our wollastonite are low iron, low LOI, and high whiteness.
Our wollastonite can be well used for ceramics, metallurgy, plastics, paper, paint, rubber, building material, glass fiber, silicone fertilizer, etc.
The application fields of wollastonite in ceramic production include glazed tiles, daily porcelain, sanitary porcelain, artistic porcelain, special ceramics for filtration, ceramic glaze, insulating high-frequency electric porcelain, light ceramic mold and bioceramics. Due to the addition of wollastonite, the performance of these ceramic products is more superior, the glaze whiteness, water absorption rate, hygroscopic expansion rate and the resistance to rapid cooling and rapid heat performance has been significantly improved, the appearance is smooth and bright, and the products have high strength, good pressure resistance, good filtering performance.
The role of wollastonite as ceramic raw material is mainly reflected in the following four aspects:
1. to reduce the firing temperature, shorten the firing cycle;
2. to reduce the shrinkage of burnt products and defects;
3. to reduce the body's hygroscopic expansion and thermal expansion in the firing process.
4. can improve the mechanical strength of products.
Our product range also covers silica, silica powder, silica fume, brucite, brucite powder, dolomite, dolomite sand & powder, calcium carbonate powder, barite powder, talcum powder, magnesium oxide, high purity magnesia, mid-grade magnesia, caustic calcined magnesia powder, caustic calcined magnesia ball, dead burned magnesia, fused magnesia, pebbles & cobbles, etc.
Free samples are always available.
We are committed to provide buyers with primary resources with the most appropriate material and competitive price to maintain a long-term stable cooperation.
