Talc - Wikipedia
Talc, or talcum, is a clay mineral composed of hydrated magnesium silicate, with the chemical formula Mg 3 Si 4 O 10 (OH) 2. Talc in powdered form, often combined with corn starch, is used as baby powder. This mineral is used as a thickening agent and lubricant. It is an ingredient in ceramics, paints, and roofing material.

2024年10月17日 · Talc, common silicate mineral that is distinguished from almost all other minerals by its extreme softness. Its soapy or greasy feel accounts for the name soapstone given to compact aggregates of talc and other rock-forming minerals. Dense aggregates of high-purity talc are called steatite.

DEFINITION FOR TALC. | U.S. Geological Survey - USGS.gov
Talc is a naturally occurring single-phase mineral having the approximate chemical formula Mg//3Si//4O//1//0 (OH)//2 and a specific type of crystal structure. Talc commonly forms by hydrothermal alteration of rocks rich in magnesium and iron (ultramafic rocks) and by low-grade thermal metamorphism of siliceous dolomites.
Talc - New World Encyclopedia
The chemical formula of talc may be written as Mg 3 Si 4 O 10 (OH) 2 or H 2 Mg 3 (SiO 3) 4. The mineral occurs as foliated to fibrous masses. Its monoclinic crystals are so rare as to be almost unknown. It has a perfect basal cleavage, and the folia are non-elastic, although slightly flexible.
