wollastonite

Wollastonite belongs to a chain silicate, but also a showed fibrous, needle-like. Because of its unique crystal structure of crystal form determines its nature, wollastonite has good insulation, while a high whiteness, good dielectric properties and high heat resistance, weathering performance. Therefore, the wollastonite is widely used in papermaking, ceramics, cement, rubber, plastic and other raw materials or filler, gas filter materials and insulation materials, metallurgical flux, as well as chemical industry, metallurgy, paper, paint and other fields. With special processing technology has managed to maintain its unique needle like structure that allows the needle like wollastonite powder adds calcium silicate boards, fire boards and other materials, impact resistance, bending folding strength, wear resistant strength are greatly increased. In the field of building materials, wollastonite will be more widely used. Ceramic grade wollastonite powder, ceramic raw materials by adding an appropriate amount of wollastonite powder, can greatly reduce the sintering temperature and shorten the firing time to achieve a low-temperature fast firing. A large number of fuel efficient, significantly reducing product costs, while improving the mechanical properties of products, reduce product cracks and warping, and increase the gloss glazed to improve embryo strength, and to improve the product qualified rate. China is the world's most resource rich countries of wollastonite. Our group maintains the country's total ore reserves of 10% of the Changbai Mountain, with 370 square kilometers of wollastonite mines, reserves of 10 million tons and excellent quality wollastonite mines. We produce wollastonite products non-toxic, chemical corrosion, thermal stability and size of stable and sound, with glass and pearl gloss, low water absorption and oil absorption values, excellent mechanical properties and electrical properties, with some reinforcing effect, fiber length easily understood separation, iron low, others.
