Washed kaolin is a refined form of kaolin clay that has been processed to remove impurities and enhance its properties. It is typically composed of fine particles of kaolinite, a type of clay mineral, and is known for its white color and low abrasiveness. Washed kaolin is commonly used in various industrial applications due to its excellent plasticity and chemical inertness. It is often utilized in the production of ceramics, paper, rubber, and paints.

When selecting washed kaolin, buyers should consider the desired purity level and particle size for their specific application.
