calciummagnesiumsilicate
Calcium magnesium silicate is a chemical compound with the general formula CaMgSi2O6. It is a member of the pyroxene group of minerals and is known by its mineral name, diopside. Diopside is a common mineral found in various geological settings, including metamorphic rocks and some igneous rocks. It typically forms in relatively low-pressure, high-temperature environments. The crystal structure of calcium magnesium silicate consists of chains of silica tetrahedra linked by calcium and magnesium ions. Its physical properties include a Mohs hardness of 5.5 to 6.5, a vitreous luster, and a color that can range from colorless to green, brown, or black, depending on impurities. Diopside is an important indicator mineral for certain metamorphic conditions and can be found in a wide range of rock types. In industrial applications, calcium magnesium silicate, often in the form of wollastonite (a related mineral that is a calcium silicate but shares some properties and uses), can be used as a filler and extender in plastics, paints, and ceramics, contributing to strength and durability.
