描述   滑石粉有什麼用？ 作為工業礦物，因為它具有耐熱，耐酸和抗電的特性。它是滑石粉中的主要成分。它也是油漆和橡膠中的重要填料。滑石粉可以保留香味，光澤，純度，柔軟度和白度，因此在商業上得到使用。滑石的一些主要市場是陶瓷，痛紙和塑料。滑石粉用於屋頂和化妝品。	Description   Talc is usually green, white, gray, brown, or colourless. Talc is a monoclinic mineral with a sheet structure like the micas. Talc has perfect cleavage that follows planes between the weakly bonded sheets. These sheets are held together only by van der Waals bonds, which allows them to slip past one another easily. This characteristic is responsible for talc’s extreme softness, its greasy, soapy feel, and its value as a high-temperature lubricant.
