Wollastonite, chemically known as Calcium Silicate, is a versatile industrial mineral with the CAS number 13983-17-0. Identified by its molecular formula CaO3Si and molecular weight 116.16, it presents as a high-quality white fine plate crystal powder.
This material is valued for its unique properties, including minimum assays of 40% CaO and 50% SiO2. Its characteristic needle crystal structure contributes significantly to its functional performance across various applications.
One of the primary applications of Wollastonite is within the coatings industry. Here, it serves effectively as a body pigment and extender, enhancing white paint brilliance and longevity. Its needle shape improves coating leveling and acts as a good suspending agent, minimizing pigment settling. It functions as a reinforcing agent in coatings and significantly improves the corrosion resistance of metallic paints. Suitable for polyvinyl acetate coatings due to its alkalinity, it also finds use in waterborne paints, primers, intermediate, and oil-based coatings. Notably, it can partially replace materials like titanium dioxide or act as a safe alternative to asbestos.
Beyond coatings, Wollastonite is widely utilized in other industrial sectors such as metallurgy, ceramics, welding electrodes, plastics, and rubber, where its properties as a functional filler and reinforcing agent are highly beneficial.
