Product:High Quality Wollastonite Powder(Calcium metasilicate)
Wollastonite is used for many different industrial purposes, including the production of:
Metallurgical: In metallurgical applications, wollastonite is used due to its low water solubility, low loss on ignition and its Ca–Si ratio. Wollastonite is commonly added to formulated powders for steel casting and welding. A CaO/SiO2 ratio of 1 readily absorbs Al2O3 that is detrimental to finished steels. The addition of wollastonite to metallurgical fluxes provides ready fusibility, good insulating qualities and low viscosity. Because wollastonite is a natural, low temperature flux, it has found acceptance in fluxing formulations used in the continuous casting of steel. When molten steel is poured continuously from a ladle or tundish, a casting powder is applied to maintain surface defects, prevents oxidation of the steel, lubricates the mold wall and absorbs harmful inclusions.
