Wollastonite Wollastonite is one of the most versatile minerals. It is a naturally found mineral that is a mixture of calcium, silicon and oxygen. However, it is majorly found in the regions of Rajasthan, Gujarat and some parts of Tamil Nadu in India The physical properties of Wollastonite include an eclectic needle looking structure which is high in brightness and has superior tones of white. It also has low moisture, oil-absorbing and high thermal stability with less solubility in water. It is low in volatility and has a high melting temperature. Wollastonite has medium hardness with rank of 4.5 on Mohâ??s scale. All of these properties make it an excellent and versatile mineral to be used in industries like plastics, paints, ceramics, construction and adhesives to mention a few. We have majorly focused our supply of Wollastonite mineral on its high-end applications in the ceramics, paints and plastics industries. Within the sphere of the plastics industry, it is a brilliant and less-expensive mineral substitute for fiberglass, carbon fiber and synthetic minerals. It is very much popular in automobile industries, as it can enhance the strength, dimensional stability, and influence resistance of car parts, aiding the manufacturers with lighter parts. Wollastonite is a calcium inosilicate mineral (CaSiO3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. It's often used in electronic equipment like connectors and computer housings because of its great insulating and fire-resistant qualities. Wollastonite mineral is customized to meet the needs of our clients' industries. Our wollastonite is anti-corrosion mineral that is ideal for paints and coatings sector. Wollastonite can improve the fire strength of ceramic tiles and sanitary ware, as well as reduce cracking and glazing faults, for ceramic manufacturers. Our Wollastonite is an excellent reinforcing filler for cement boards and fire-insulating boards in the building industry. Aryan Tiles is confident in the quality of its Wollastonite minerals. Wollastonite has proven to be the most adaptable material used in various key sectors, and the market for it is constantly expanding.
What is Wollastonite? Wollastonite is a calcium, silicon, and oxygen-based industrial mineral. It is generally white, although it can also be colorless or gray. CaSiO3 is the molecular formula of Wollastonite. 2.86-3.09 is the specific gravity of it. What are the Purposes of using Wollastonite? Wollastonite increases weather resistance, lowers brightness and coloring, and works as a flatting and suspension agent, as well as performing as a smoothing and suspending agent. What are the Specifications?

Wollastonite is used in the manufacture of ceramics. It reduces firing and drying shrinkage, and lowers the temperature at which the glasslike stage is constructed. It minimizes instability and glaze problems in ceramic production and reduces shrinkage and gas expansion. What are the other Applications? In spite of being used in ceramics, wollastonite is also used in plastics, steel, and in the production of paints and coatings.
Ceramics: wollastonite can be used in a variety of ceramic applications including ceramic glazes and bodies, enamels, frits, fluxes and in sanitaryware. This industrial mineral is a source of cao to alkaline glaze formulations to improve the strength of the glaze. Wollastonite also has a low loi (< 1%) which gives minimal gas evolution during firing resulting in a smooth surface with diminished pinholing. Due to its acicular structure, wollastonite improves green strength and reduces crazing and checking especially during rapid heating and cooling. It has a low sintering temperature (approximately 991-1196c) which is comparable to that of most natural frits. Specification: Sio2:45-56%, Al2o3

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.
Description: Wollastonite has bright color and high reflectivity, which could be suitable for the production of high-quality white paints and clear transparent paints.wollastonite is a good additive with higher fraction of color coverage and homogeneous distribution. Based on its UV resistance, it is widely used in interior wall paints, exterior wall paints, special paint (especially fireproof paint) and latex paints. Wollastonite powder which can partly replace titanium dioxide to produce paint coating can not only improve the color of products, improve the gloss of the paint, enhance the anti-tensile ability of the paint, reduce the crack, but also can reduce the oil absorption and enhance the anti-corrosion ability. The finer particle size, higher whiteness and pH value can greatly improve the color and coating property of the paints, which can be helpful to produce anticorrosive coating for metal equipment such as steel pieces. Wollastonite can also be used as the filler of paint coating to improve the physical and chemical properties, durability and weather resistance and reduce the fracture and aging of the paint. The quality requirements of wollastonite in paint coatings are: SiO2 49%min, CaO 45%min, Fe2O3 0.2%, 325 mesh, mineral powder oil absorption amount is 20-25g/100g, water soluble matter 0.5%, water extraction pH value is 7-9, whiteness 90%.
