Industry analysis reveals a steady growth in demand due to its unique physical and chemical properties, such as low oil absorption, high brightness, low moisture content, and needle-like morphology. Such properties position it as a preferred choice in polymer composites, ceramics, paints, coatings, and metallurgy ( ScienceDirect, 2023 ). Technical Parameters of Wollastonite Powder Parameter Unit Value Industry Standard Purity (CaSiO 3 ) % ≥98 ≥94 Moisture Content % ≤0.5 ≤1.0 Whiteness % 86-93 ≥85 pH Value - 7-8.5 6.5-8.5 Oil Absorption g/100g 35-40 40-45 Specific Gravity g/cm 3 2.85-2.95 2.8-2.95 Mesh Size mesh 325/600/1250 300/600/1200+ Color - Grey White/Grey Application Scenarios for Wollastonite Powder Polymer Composites: Used for reinforcement and dimensional stability in plastics, automotive parts, and electrical insulators ( CompositesWorld ). Ceramics: Preferred filler for floor and wall tiles, sanitary ware, and specialized refractories for its low thermal expansion and high strength. Paints and Coatings: Enhances scratch resistance, improves brightness, and prevents cracking in emulsion paints and protective coatings. Metallurgy: Important fluxing agent in steel-making and an alternative to asbestos in high-temperature insulation systems. Construction: Used in fire-resistant boards, cement, adhesives, and joint compounds. Friction Products: Ingredient in brake pads and clutches for automotive and industrial applications. Other Industries: Including agriculture as a soil conditioner and glass manufacturing.

What is the chemical composition of Wollastonite Powder ? Answer: The main component is calcium metasilicate (CaSiO 3 ). It may also contain trace amounts of iron, magnesium, and aluminum oxides. 2. What mesh sizes are available for Wollastonite Powder ? Answer: Standard sizes include 325 mesh, 600 mesh, and 1250 mesh, suitable for diverse manufacturing needs. 3. What are the recommended installation or mixing standards for ceramic applications? Answer: For glazes, a 5-15% addition is typical. Consistent particle size is required for optimal dispersion. 4. What is the CAS number and is Wollastonite Powder safe? Answer: CAS No.: 1344-95-2. Studies confirm its non-toxicity and safe use as a mineral additive ( NCBI ). 5. How does Wollastonite Powder compare to talc or kaolin as a filler? Answer: With a higher aspect ratio and better reinforcing properties, Wollastonite Powder offers increased mechanical strength in composites (see Journal of Elastomers & Plastics ). 6. What is the recommended storage condition for maintaining product quality? Answer: Store in dry, ventilated areas. Avoid contact with moisture and acids to retain whiteness and flowability. 7. Does Wollastonite Powder affect rheological (flow) properties in paints? Answer: Yes, it improves thixotropy, viscosity control, and spreadability, resulting in better finished surface.
