Description
Any of the silicates of calcium. Calcium silicate occurs naturally in several minerals: Wollastonite, Diopside, Anorthite, lawsonite and Tremolite. Calcium silicates are used in the manufacture of Glass, Porcelain, molecular sieves, Wallboard, and Portland cement. Wollastonite is used as a bubble-free white opacifier in glazes. Calcium silicates are also used as fillers for paper and plastics. In general, they are highly absorbent.
Synonyms and Related Terms
