Wollastonite is a metasilicate mineral of calcium and a new industrial mineral raw material that is mainly used in ceramic industry. Its secondary applications include metallurgical protection slag and coatings as well as welding rod coatings, asbestos substitutes, grinding adhesives, glass ingredients and fillings for producing rubber, plastic, insulation materials and paper.
Nov 01, 2002· Wollastonite has a strong buffering effect in acid solutions due to the release of calcium ion. Wollastonite Grades The filler uses for wollastonite are dictated primarily by the length of the wollastonite needles in the ore and the extent to which this shape is preserved during grinding of the finished products.
Typical Applications. Wollastonite has been found useful as a soil conditioner and an additive to plant fertiliser for its reactivity in acid conditions. As opposed to lime or calcite, it offers long-term protection against the acidification of soils. In some countries, wollastonite has also found use as an inert carrier for pesticides and insecticides.
cleavage properties, wollastonite breaks down during crushing and grinding into needle-shaped particles. The aspect ratio, or the ratio of needle length to its diameter, is a measure of the acicularity of the wollastonite product and is a key market specification. Wollastonite has a wide range of uses such as in ceramics, wollastonite-based

Wollastonite (CaSiO 3 ) has been synthesized by the solid state reaction method at a temperature range of 1050-1250℃ from local raw materials, e.g. silica sand and limestone as well as pure chemicals in the form of carbonate and quartz with and without B 2 O 3 adding as a mineralized.
Natural wollastonite however, may contain trace or minor amounts of various metal ions such as aluminum, iron, magnesium, manganese, potassium and sodium. Any of these ions may partially substitute for calcium if they are present. Wollastonite is rarely found by itself, and ore zones in the major deposits contain 20-98% wollastonite.
