Talc

Talc, common silicate mineral (Mg3Si4O10(OH)2) that is distinguished from almost all other minerals by its extreme softness (it has the lowest rating on the Mohs scale of hardness). Its soapy or greasy feel accounts for the name soapstone given to compact aggregates of Talc and other rock-forming minerals. Dense aggregates of high-purity Talc are called Steatite. Iran is one of the best Talc suppliers in Middle East. Marjan Mineral Company can provide all necessary conditions for Talc exporting. Having good commercial relations with the most of Iran's Talc supplier is Marjan Mineral Company's honor. Read more . . .


Talc Usages:
Talc basically has five characteristics that make it a valuable mineral for industrial and domestic applications.
  • Softness
  • Chemical inertness
  • Lamellarity
  • Whiteness
  • Affinity for Organic Chemicals

In fact, Talc is found in everything from animal feed to tires, and has been for millennia. As long as 15,000 years ago, cave dwellers used Talc in their paints. For at least 5,000 years, it has been used in cosmetics, especially as a skin lightener, and 1,000 years ago, the Chinese began using it in their glazed pottery. Listed below are several of Talc’s uses for the industries of the world:
  • Paper Industry: Talc's number one consumer is the Paper Industry. It is used as filler and coating for paper products. Furthermore, Talc helps control the paper's pitch while the paper is being processed. It improves paper smoothness, water retention in certain papers, and printability and runnability for coated papers.
  • Ceramics Industry: The Ceramics Industry is another Talc consumer. The glazing and bodies of the ceramics rely on Talc to give ceramics their gloss, whiteness and shape. Dinnerware, Sanitary ware, tiles, porcelain, and electrical insulation are all part of ceramics made with Talc. It is also used as a flux and to control thermal expansion - particularly in catalysts and particulate filters. Read more . . .
