Demand for Talc to Rise Significantly from Key End-use Industry Sectors
Verfasser: yogesh on Friday, 5 April 2019Talc is a mineral composed of hydrated magnesium silicate and is an important industrial and commercial mineral. It has broad applications as an industrial mineral due to its resistance to heat, electricity and acids and oil and grease adsorption. Talc has extensive commercial use because of its luster, softness, purity, fragrance retention, softness and whiteness. It is the softest known mineral and has a rating of 1 on the Mohs hardness scale. It can be scratched by a fingernail and is also sectile that means it can be cut by a knife. It has a specific gravity of 2.5 -2.8 and has clear luster. Talc is slightly soluble in dilute mineral acids and insoluble in water. It is a metamorphic mineral and occurs due to metamorphism of magnesium minerals such as olivine, amphibole, serpentine and pyroxene in presence of water and carbon dioxide. Talc is a tri-octahedral layered mineral and has a similar structure to that of pyrophyllite.
