Industry Trends of Wollastonite Powder

**Wollastonite Powder** is rapidly emerging as a multipurpose mineral filler in advanced manufacturing. 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).

Professional FAQ on Wollastonite Powder Specifications and Use

1. What is the chemical composition of Wollastonite Powder?
Answer: The main component is calcium metasilicate (CaSiO₃). 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.
