Product Description Company ProfileProduct DescriptionWollastonite powder, with a chemical formula of Ca3(Si3O9), is a natural mineral substance characterized by its high content of calcium oxide (CaO, approximately 48.25%) and silicon dioxide (SiO2, roughly 51.75%). It exhibits a relative density ranging from 2.78 to 2.91 and boasts a white hue tinged with gray or red. The mineral occurs in the form of plate-like, radial, or fibrous aggregates, displaying a vitreous luster and a pearly luster on cleavage surfaces.Under ultraviolet light, wollastonite powder emits a fluorescent or phosphorescent glow, and its melting point stands at approximately 1540°C. Renowned for its needle-like and fibrous crystalline structure, high whiteness, anhydrous composition, high melting point, low coefficient of thermal expansion, corrosion resistance, weathering resistance, and excellent mechanical and electrical properties, wollastonite powder finds extensive applications across various industries.SpecificationItemValuePlace of OriginChinaApplicationWidely used in composite materialsHardness4.5-5SiO2 Content (%)51-53Fe2O3 Content (%)0.2Al2O3 Content (%)0.7% MaxMgO Content (%)0.8CaO Content (%)41-43Whiteness88-90Refractive Index (%)1.63Packing25kg/bag;Customized packagingPortTianjinDelivery time7-15daysApplicationIn the ceramics, coatings, plastics, and rubber sectors, wollastonite powder serves as a filler material, enhancing the physical and chemical properties of products.
