Available in nature as a mineral labelled as “wollastonite”, the calcium metasilicate is a product of remarkable interest in various fields of application.
The construction industry uses wollastonite for its fire and impact resistance and low thermal conductivity; in the plastics industry it is used as filler and acts as a strengthner. In the field of inorganic coatings , wollastonite is a pigment that brings whiteness and resistance to corrosion.
Therefore, in order of importance the ceramic sector emerges as one of the industry where wollastonite is mostly used. In fact, in the ceramic sector, differently from calcium carbonate, it is used in mixtures for the production of porcelain since it doesn’t develop cooking gas in this way decreasing the risk of air bubbles. A few percentage points of wollastonite in mixtures limit linear shrinkage up to 0.5%. Moreover, the production of frits and glazes is characterized by a great use of the mineral. Products that contain wollastonite have good resistance to thermal shock, thanks to the low thermal conductivity of wollastonite itself.
C.B.C. Group uses and sells wollastonite for all uses listed.
