talc is a mineral of choice in many industrial uses
Talc is an hydrated magnesium silicate, belonging to the subclass of phyllosilicates. Its crystals are thin and lamellar forming, when massive, wide range of colours (i.e.: white, pink, green, grey or black). Talc can be found in various grades, different by purity, colour and lamellarity. Its main characteristics are: it’s naturally hydrophobic and lipophilic, it’s chemically inert, resisting very well to acids and bases; it's the softest mineral; it’s a good electric and thermal insulator and it’s neither flammable nor explosive. Thanks to these characteristics, talc is a mineral of choice in many industrial uses.
