Although all talc ores are soft, platy, water repellent and chemically inert, no two talcs are quite the same. Talc is a vital part of everyday life. Talc has many used and its added as a filler to almost every other thing e are using household. like paints, plastics, insecticides etc.
Talc is a magnesium sheet silicate with the chemical formula Mg3Si4O10(OH)2. Talc composition does not contain hydroxyl groups or active ions, which explains talc’s hydrophobicity and inertness.
Talc is practically insoluble in water. It is inert. Although it has very little chemical reactivity. Above 900°C, talc progressively loses its hydroxyl groups and above 1050°C, it re-crystallizes into different forms of enstatite (anhydrous magnesium silicate). Talc’s melting point is at 1500°C.
