Adding appropriate wollastonite (either medium-grade or low-grade) in ceramic raw material is beneficial to greatly reduce firing temperature and shorten firing time of finished product, achieve low-temperature once firing, save a great deal of fuel and product cost. Because wollastonite products do not include alkali metal, it shows excellent electric insulation property, as well as high impact strength resistance and dimensional stability, has a wide application in the precision ceramic industry and art ceramic industry. In glaze mud material, wollastonite, instead of white pigment, can increase gloss of glaze, reduce viscosity of glaze mud and mitigate cost greatly. In ceramic products, wollastonite can avoid fracture, hair cracking, breakage or defects of ceramic glaze. Due to linear thermal expansion, it can reduce the flexural degree of products.
