Talc Powder (Hydrous Magnesium Silicate) General Description:

a) A mineral which occurs naturally throughout the world. It has a platy structure
b) Talc is a metamorphic mineral resulting from the metamorphism of magnesian minerals such as serpentine, pyroxene, amphibole, 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.
c) Talc is primarily formed via hydration and carbonation of serpentine, via the following reaction;
serpentine + carbon dioxide = talc + magnesite + water
Mg3Si2O5 (OH)4 + 3CO2 = Mg3Si4O10 (OH)2 + 3 MgCO3 + 3 H2O

    TECHNICAL DATA SHEET TDS RANJANA TALC :-

  • DESCRIPTION
    • Talc is a soft, lamellar inert mineral, which occurs typically as magnesium silicate. The Talc grades exhibit good purity and chemical stability.

  • USES
    • These properties typically render the Talc B grades an ideal carrier and functional extender in cosmetics and pharmaceuticals. Further applications include high performance paints and coatings, thermoplastic polymers, waxes, and slip agents.
