Areas of Use :
According to the “Mohs scale”, which classifies the substances in the world according to their hardness in 10 degrees and where the human nail has a hardness degree of 2.5, talc is ranked 1st, earning the title of the softest known mineral. Classified by mineralogists as “cuttable with a knife-sectile”, talc has the formula Mg3 Si4 O10(OH)2 and is called “magnesium silicate hydroxide”. Talc, which has a specific gravity of 2.5-2.8, has a semi-transparent-opaque appearance. It feels slippery when touched by hand. It is not affected by acids and does not dissolve in water. In its pure form, it is a very bright white colored, chemically inert, high melting point, low heat and electrical conductivity and high absorption power mineral. Although it is originally white, it can be greenish, bluish, gray in color depending on the other substances it contains, which will be mentioned later. In terms of its formation, it is a metamorphic mineral (2,3). Talc is used in amounts expressed in tons in the rubber, ceramic, pesticides, paint, casting, plastic, insulation, paper, cement, cosmetics and food industries, apart from medical use today (2,4).
