Crude China Clay
Crude China Clay, also known as raw kaolin, is a naturally occurring clay mineral mainly composed of kaolinite. It is obtained through mining and basic extraction processes without extensive refining or chemical treatment. Crude China Clay is generally white, off-white, or light-colored and has good natural plasticity, low shrinkage, and excellent chemical stability. It is widely used as a basic raw material in ceramics, tiles, sanitaryware, refractories, paper, paints, rubber, and construction products.
Its quality depends on factors such as kaolinite content, particle size, brightness, moisture, and impurities. Common impurities include quartz, mica, feldspar, and iron compounds. Because of its natural properties and versatile applications, crude china clay is an important industrial mineral used in both traditional and modern manufacturing processes.
