The Mineral Talc: Uses, Properties, Photos - Geology

Talc: Talc is a phyllosilicate mineral that cleaves into thin sheets. These sheets are held together only by van der Waals bonds, which allows them to easily slip past one another. This characteristic is responsible for talc's extreme softness, its greasy to soapy feel, and its value as a high-temperature lubricant.

Talc - Wikipedia

Talc is a mineral that results from the metamorphism of magnesian minerals such as serpentine, pyroxene, amphibole, and olivine, in the presence of carbon dioxide and water. This is known as "talc carbonation" or "steatization" and produces a suite of rocks known as talc carbonates.

Talcum | Whitetalc

Talc or talcum is a clay mineral composed of hydrated magnesium silicate with the chemical formula H2Mg3(SiO3)4 or Mg3Si4O10(OH)2. In loose form, it is (in ratio with or without corn starch) one of the most widely used substances known as baby powder. Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 1 as the hardness of talc.
