Wollastonite is a calcium inosilicate mineral. The powder is obtained by processing wollastonite bearing rocks. Its particles generally have a needle like or acicular structure. Chemically, wollastonite has the formula CaSiO₃. This relatively simple chemical composition, combined with its crystal structure, endows it with distinct physical and chemical properties. The needle like shape of the particles is a key feature that contributes to its performance in various applications.
Wollastonite powder is used in the ceramic industry to improve the quality of ceramics. It can reduce the firing temperature, shorten the firing time, and enhance the mechanical properties of ceramics. In the production of tiles and porcelain, wollastonite helps to create products with better wear resistance and surface finish.When added to rubber, wollastonite powder can act as a reinforcing filler. It can improve the tensile strength, tear resistance, and hardness of rubber products, making them more suitable for applications like tires, conveyor belts, and seals.In paints and coatings, wollastonite powder can improve the hiding power, durability, and weather resistance. Its needle - like structure can also enhance the film - forming properties of coatings, providing a more uniform and protective coating layer.
