1.Introduction
Talcis a kind of of magnesite silicate minerals, mainly containingmagnesium oxide and silicon dioxide. The color of this product iswhite, gray. Aggregate usually is in coarse or fine squamose fromand dense lump form. Density as follows: 2.58 to 2.83 hardness: 1.0with pearls or oily luster, satiny touching, translucent ortransparent, heated to 600 ℃ waterbegin to evaporate and discharge completely when880 ℃ to970 ℃ .And it become enstatite.
2.Feature
Talcumpowder has some excellent physical and chemical properties,such asthe lubricity, fire resistance, acid resistance, insulation, highmelting point, good covering power and soft, good luster, strongadsorption force and etc .
