滑石, also known as talc, is a soft mineral composed mainly of magnesium, silicon, and oxygen. It is commonly used in various industries, including cosmetics, pharmaceuticals, and food products, due to its ability to absorb moisture and reduce friction. In its natural form, 滑石 appears as a white or light-colored powder. It is often found in metamorphic rocks and is mined in several countries. Additionally, 滑石 is a key ingredient in baby powder and is used in the production of ceramics and plastics for its lubricating properties.
