 | Wollastonite in ceramic raw materials can achieve fast single firing in low temperature by reducing the sintering temperature and shortening the sintering time, which saves plenty of fuel and decreases production cost significantly. Since Wollastonite product is free of alkaline metal, it possesses high electrical insulation, high impact resistance and shape stability. With these properties, Wollastonite can be applied in precision ceramics and craft ceramics. Filled in glaze material to improve glaze luster and reduces the glaze mud viscosity as the replacement of white pigment, which lowers the cost drastically. Filled in ceramics products to prevent ceramic from micro crack, damage and glaze defects. Furthermore, it can reduce the deflection owning to its linear thermal expansion. |
