Description Wollastonite has many excellent performances including fine insulativity, high whiteness,good dielectric property and better heat-resisting and weather-resisting performances. Wollastonite can be widely used in the fields of ceramics, chemical industry, metallurgy, papermaking, plastics, coating and other fields. Our wollastonite have many advantages such as lower Fe content, lower LOI and higher whiteness. Our wollastonite is chosen by manpower. It is defined into two classes-Class I and Class II based on different Ca contents. Item Typical Value SiO2 (m/m,%) 57-60% CaO (m/m,%) 30-35% Fe2O3 (m/m,%) 0.5%max MgO (m/m,%) 1.5%max LOI. 2-4% Whiteness 85-88 Shape Powder
Applications: This product can be used in ceramic glazes. Adding wollastonite powder in ceramic can reduce the sintering temperature and shorten the firing time, which can save a lot of fuel, improve the products mechanical properties, reduce crazing, cracking, breakage, enamel defects and other problems. It can also improve the embryo strength, reduce the products weight, increase the luster of ceramic glazes, reduce the mud viscosity, which can reduce costs, and improve the quality and yields of ceramic products. With the excellent insulation properties, high impact strength and shape stability, it can be used in insulating ceramic industry and the craft ceramic industries Our advantages: 1.lower Fe content 2.Lower loss on ignition (LOI) 3.Fewer surface defects 4.Improved shrinkage control 5.Higher impact strengthCarbon 6.Faster drying times 7.higher whiteness
Dead Burned Magnesite is produced by natural magnesite after high-temperature being calcined in the vertical kilns.It is an ideal material for making bricks and unshaped refractory materials,its finished products are used in Steelmaking furnaces,eletric furnace bottom and ramming furnace lining.

Wollastonite is chemically a Calcium MetaSilicate (CaSiO3),Wollastonite with dense shaped ceramic structure can improve the mechanical strength, reduce the wet expansion coefficient, improve the bodys strength and molding quality, and reduce the sintering temperature so that rapid sintering in low temperatures, the purpose of energy saving and efficiency can be achieved. In the glaze making industry, wollastonite can improve the whiteness and fluidity of glaze, and reduce the defects of products. Wollastonite can be used to produce all kinds of electroceramics, architectural porcelain/ceramics, daily-use ceramics and brake pads, etc. Nearly half of the world's annual output amount of wollastonite is used in ceramics as the largest production field.Wollastonite in China is mainly used in glazed bricks and ceramic bodies, copying more than 50% of the total consumption amount of wollastonite.
