Wollastonite powder is a naturally occurring calcium silicate mineral used in various industries, including ceramics, plastics, paints, coatings, and construction materials. Here are some common specifications for wollastonite powder:

1. Chemical Composition:

   • Wollastonite is primarily composed of calcium, silicon, and oxygen. The chemical formula is often written as CaSiO3.
   • High-purity wollastonite typically contains over 90% calcium silicate.

2. Particle Size:

   • Wollastonite powder can come in various particle size distributions, depending on its intended use. Common particle size ranges include:
     • Fine wollastonite: Typically below 10 micrometers
     • Medium wollastonite: 10 to 40 micrometers
     • Coarse wollastonite: Above 40 micrometers

3. Whiteness:

   • Whiteness is an important property for many applications of wollastonite, especially in the ceramics and coatings industries. It is often specified as a percentage.
