Сurrent trends in the use of natural and synthetic wollastonite. Rerview

The crystalline phases of the CaO-SiO2 system and polymorphic modifications of calcium metasilicate (wollastonite) are analysed. The physical, crystallographic characteristics and structural parameters of the wollastonite crystal lattice are presented. The features of the use of natural and synthetic wollastonite in various industries are considered. The role of wollastonite as a reinforcing material, which depends on the morphology of its crystals, is highlighted.
