Ultrafine talc powder

Talc is often white, light green, slightly pink, light gray in color, and the darker the color with more impurities, even dark gray or black. Ores are often in the form of flakes, fibers, and dense blocks, with a pearl luster or oil luster. In theory, talc has a Mohs hardness of 1, a density of 2.7g/cm ³, and a sliding sensation. Talc has a significant thermal effect when heated. Theoretically, it loses its adsorption at 120-200 ℃, loses some structural water at 600 ℃, and is completely dehydrated at 1050 ℃.
Talc and talc powder have the following characteristics: electrical insulation performance, heat resistance, chemical stability, oil absorption and covering power, lubricity, hardness variability, and machinability. Widely used in fields such as papermaking, plastics, rubber, cables, ceramics, coatings, and building materials.
