Industrial Talc Mineral Powder Dealers in Mia, Alwar

Also known as Soapstone, Talc Powder is hydrated silicate of magnesium (Mg3Si4O10(OH)2). The Talc Powder is the softest mineral with characteristic soapy feel and 1 moh̢۪s scale of hardness. The Talc Powder can be easily scratched and cut by one̢۪s nails. General Properties It is neither explosive nor flammable.Melting point of Soapstone is 1500oC.Pearly luster and its platyness gives excellent opacity to the end products Steatite, Talc, Soapstone are the three terms used in trade for one and same mineral.Soapstone is practically insoluble in water and in weak acids and alkalis.Above 900oC, Soapstone progressively loses its hydroxyl groups and above 1050oC, it re-crystallizes into different forms of enstatite (anhydrous magnesium silicate).Although it has very little chemical reactivity, talc does have a marked affinity for certain organic chemicals, i.e. it is organophilic.
