    Noticeable Acicular Excellent Stability Mesh 1250 Calcium Metasilicate

    Grade:HGWD-1250

    Product:High Quality Wollastonite Powder(Calcium metasilicate)

    Decriptions
    Wollastonite is a white to yellowish-brown naturally occurring mineral. It has good strength, firing characteristics and ability to reduce crazing. It is comprised chemically of calcium, silicon and oxygen. It's molecular formula can be expressed as CaSiO3 or as CaO.SiO2. It is commonly referred to as calcium metasilicate according to the now obsolete classification of silicates as oxyacids of silicon, a salt of hypothetical metasilicic acid: H2SiO3. It has a theoretical composition of 48.28% CaO and 51.72% SiO2.

    Wollastonite is an inorganic needle-like mineral, and wollastonite products have very noticeable acicular and long fiber structures .It is characterized by non-toxicity, chemical corrosion resistance, good thermal stability and dimensional stability, glass and pearl luster, low water absorption and oil absorption value, excellent mechanical and electrical properties,even reinforcing effect. Wollastonite products with long fibers and easy separation, low iron content and high whiteness.
