Product Details

Product Description

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 was one of the most widely used substances known as baby powder, along with corn starch. It occurs as foliated to fibrous masses, and in an exceptionally rare crystal form. It has a perfect basal cleavage, and the folia are not elastic, although slightly flexible.

Formation

Talc is primarily formed by hydration and carbonation by this reaction:

     serpentine             carbon dioxide                 talc                          magnesite             water

2 Mg3Si2O5(OH)4+        3CO2               → Mg3Si4O10(OH)2 +     3 MgCO3     +     3 H2O
Talc can also be formed via a reaction between dolomite and silica, which is typical of skarnification of dolomites by silica-flooding in contact metamorphic aureoles:
     dolomite               silica           water                   talc                               calcite                carbon dioxide
3 CaMg(CO3)2  +   4 SiO2    +     H2O       →    Mg3Si4O10(OH)2    +   3 CaCO3       +         3 CO2

Applications

Talc is a mineral composed of hydrated magnesium silicate with the chemical formula H2Mg3(SiO3)4 or Mg3Si4O10(OH)2. Talc is used in many industries such as paper making, plastic, paint and coatings, rubber, food, electric cable, pharmaceuticals, cosmetics

Uses Dusting powder, either alone or with starch or boric acid, for medicinal and toilet Preparations; excipient and filler for pills, tablets and for dusting tablet molds; clarifying liquids by filtration. As pigment in paints, varnishes, rubber; filler for paper, rubber, soap; in fireproof and cold-water paints for wood, metal and stone; lubricating molds and machinery; glove and shoe powder; electric and heat insulator.
