The company is one of the major Manufacturers and Suppliers of Wollastonite Powder in Beawar. The Wollastonite Powder form low-melting points with more refractory phases such as Al2O3 and MgO. The Wollastonite Powder (CaO.SiO2) have a lower melting point (1540°C for pure Wollastonite). The usage of Wollastonite Powder in ceramic bodies can amount to as much as 40% or more. Wollastonite Powder Serve as a reliable sintering aid to vitrified bodies. The addition of Wollastonite Powder results in many positive effects such as less fired shrinkage, low water absorption, lower fast firing temperature, higher green strength, less cracking and shorter firing times. Wollastonite Powder can also replace limestone and silica sand in a glass batch where it reduces the melting temperature and inhibits scum and seed formation. This can be important in the production of specialty glasses and fiberglass. Wollastonite Powder are minerals comprised chemically of calcium, silicon and oxygen. The molecular formula of Wollastonite Powder can be expressed as CaSiO3 and are commonly referred to as calcium meta-silicate. The Wollastonite Powder contain 86-89% of calcium meta-silicate.
