Contact SupplierTalc is the softest mineral (occupying place 1 in the Mohs` hardness scale) known on our planet earth. It is lamellar, platy, organophilic, water repellent with special thermal and mechanical properties. It has a high capacity for absorbing organic substances. It is also acid & alkali-resistant, chemically inert and non-toxic. Talc has neither aroma nor taste. This makes it a very essential mineral in our day-to-day life. Talc is a hydrated magnesium silicate [chemical formula is Mg3Si4O10(OH)2. Also known as Steatite. It is the main component of soapstone. Its crystals usually develop massive, leafy aggregates with laminar particles. Its silicate layers lie on top of one another without having a chemical bond but are bound to each other by weak Vander Waals forces. This structure gives talc the platy appearance and its characteristic greasy or soapy feeling hence the name soapstone. Industrial
