White Wollastonite Powder is used widely in plastic, ceramics, rubber, and paint industries to enhance surface color, tensile strength, and heat performance of products. High brightness and whiteness, low volatile content, low moisture, and oil absorption are some of its features that make sit high on demand. Chemical Formula : CaSiO3 PHYSICAL PROPERTIES : Appearance- White fine powder Sp. gravity- 2.8 - 3.0 PH Value- 8.0 - 8.5 Fineness- Passes 325 mesh CHEMICAL COMPOSITION : SiO2 Content- 6 5% Iron Content- 0.5% Water Content- 1% Industrial Applications : Used as Filler In Rubber, Plastics, Electric insulators, powder coatings etc.

Wollastonite is chemically a Calcium Meta Silicate (CaSiO3), it is a naturally occurring white & acicular (needle shaped) mineral, with mohs hardness of 4.5. In addition to Wollastoniteâ??s unique morphology, it is alkaline, inert, has low loss on ignition, low water solubility, low co-efficient of linear thermal expansion and a melting point of 15400c. It also improves tear strength, dielectric properties and retains mechanical properties at elevated temperatures.

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.
