Caolín, also known as china clay, is a soft, white clay that is named after the Gaoling (Kao-ling) village in Jingdezhen, Jiangxi Province, China. It has been used for centuries, especially in the production of porcelain and fine china, which explains its alternative name.
Chemically, kaolin is composed mainly of kaolinite, a hydrous aluminum silicate mineral. Its chemical formula is Al₂Si₂O₅(OH)₄. This mineral gives kaolin its unique properties. It has a fine particle size, high whiteness, and excellent plasticity when wet, making it ideal for various applications.
In the ceramics industry, kaolin is a fundamental raw material. It helps to create the smooth texture and pure white color that is characteristic of high - quality porcelain. In the paper industry, kaolin is used as a coating pigment. It improves the brightness, smoothness, and printability of paper. Additionally, kaolin finds applications in the paint, rubber, and plastic industries. In paint, it acts as a filler, enhancing the paint's durability and hiding power. In rubber and plastics, it can improve the mechanical properties of the final products. Overall, kaolin plays a crucial role in multiple industrial sectors due to its special properties.
