Wollastonite is a kind of triclinic crystal system, fine plate crystal, the aggregate is radial or fibrous. The color is white, sometimes with a light gray, light red tone. Glass luster, cleavage surface is pearl luster. The hardness is 4.5-5.5, and the density is 2.75-3.10g/cm3. Completely soluble in concentrated hydrochloric acid. Generally, it is resistant to acid, alkali and chemical corrosion. Moisture absorption is less than 4%. Low oil absorption, low conductivity and good insulation. Wollastonite is a typical metamorphic mineral, which mainly occurs in the contact zone between acid rock and limestone, and coexists with Wushan stone and garnet. It is also found in the deeply metamorphosed calcareous crystalline schist, volcanic extrusions and some alkaline rocks. Wollastonite is a kind of inorganic needle like mineral, which has the characteristics of non-toxic, 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 and certain reinforcing effect.
