Wollastonite Product Specifications

  Wollastonite is a naturally occurring calcium inosilicate mineral (CaSiO₃) valued for its needle‑like crystal structure, high whiteness, and excellent thermal stability. When processed into fine powders or fibers, it provides reinforcement, dimensional stability, and improved mechanical strength across a wide range of industrial applications. In ceramics, wollastonite enhances glaze quality, reduces shrinkage, and improves resistance to thermal shock. In plastics and rubber, it acts as a functional filler, increasing tensile strength and reducing warpage, while in paints and coatings it contributes to durability, brightness, and corrosion resistance
