Details : Wollastonite is an industrial mineral comprised chemically of calcium, silicon and oxygen. Its molecular formula is CaSiO3 and its theoretical composition consists of 48.28% CaO and 51.72% SiO2. It is used in various industries such as Plastics, Construction, Paints & Coatings, Ceramics, Mettalurgical & Friction.   Plastics : Wollastonite improves the durability of the composite due to its acicular or needle-like structure. It also enhances electrical insulating properties, adds fire resistance, and improves dimensional stability. Finer particle size grades provide improved scratch and impact resistance compared to other materials.   Construction : Wollastonite has found application as a substitute for asbestos in fire-resistant building products used in the construction industry. As a functional additive, wollastonite improves flexural and impact strengths. Wollastonite finds application in interior and exterior construction boards, roof tiles, shaped insulation products, sheets, panels and sidings.   Paints and Coatings : In coatings, fine acicular particles act as a good flattening agent and allow paint to settle out after application to produce a dry film of uniform thickness, and the interlocking particles improve toughness and durability of the coating with excellent tint retention, scrub, and weather resistance. The acicular structure and alkaline nature of wollastonite also make it an ideal auxiliary pigment in industrial coatings and primers for improved corrosion resistance.   Ceramics : Wollastonite can be used in a variety of ceramic applications including ceramic glazes and bodies, enamels, frits, fluxes and in sanitary-ware. It has a low sintering temperature (approximately 991-1196°C) which is comparable to that of most natural frits.   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. 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.   Friction : Due to its physical structure and non-hazardous properties, wollastonite is used as a reinforcing additive in many friction applications. It is also a partial/full replacement for asbestos, milled fibres, chopped glass and synthetic materials. Its primary application is in semi-metallic and nonasbestos formulations for truck blocks, drum linings, disc pads and friction paper. Benefits of using wollastonite in a friction formulation include improved physical and mechanical properties, reduction or elimination of cracking, improved pre-form strength, improved friction stability, noise reduction and reduced raw material cost.
