Formula: Mg3Si4O10(OH)2
 
Talc is a mineral composed of hydrated magnesium silicate with the chemical Mg3Si4O10(OH)2. In loose form, it is the widely used substance known as talcum powder. It occurs as foliated to fibrous masses, its monoclinic crystals being so rare as to be almost unknown. Talcum has a perfect basal cleavage, and the folia are non-elastic, although slightly flexible. It is sectile and very soft, with a hardness of 1 (Talc is the softest of the Mohs’ scale of mineral hardness, and can be easily scratched by a fingernail). It has a specific gravity of 2.5-2.8, a clear or dusty luster, and is translucent to opaque.
Talcum is not soluble in water, but it is slightly soluble in dilute mineral acids. Its colour ranges from white to grey or green and it has a distinctly greasy feel. Its streak is white.
Micronized talc has improved whiteness parameters. Furthermore, the natural mixture of block and flake particles has good micro-magnetic properties and the ability to make thick packs in coatings with minimal binder requirement (low dose DOP and oil absorption).
The main applications are: varnish-paint materials and decorative materials, adhesives, adhesives, whales, rubber and plastics, anti-corrosive preparations, protective coatings. This product is used as a functional mineral in the production of ceramics, paints, coatings, rubber and asphalt industry.
