KAOLIN(CAS: 52624-41-6)

Kaolin is a natural clay mineral with a white, earthy appearance. Chemically, it is a hydrated aluminum silicate. Its crystalline form is monoclinic. Kaolin has a relatively low molecular weight (approximately 90 g/mol) and is insoluble in water but soluble in acids. It has low reactivity and is often used in the pharmaceutical and food industries due to its non-toxic and inert nature.

KAOLIN is not typically synthesized but is naturally occurring as a clay mineral. However, synthetic kaolins can be produced by weathering silicate minerals or by hydrothermal synthesis using kaolinite clays as a starting material. These processes often involve heat treatment and water to transform other aluminosilicate minerals into the desired kaolin structure.

KAOLIN is widely used in various industries. In pharmaceuticals, it is used as a tablet excipient and in the production of certain medications. In polymers, it acts as a filler and improves properties like opacity and barrier. It is also used in sensors and semiconductors for its electrical and thermal properties, and in the paper industry as a filler and coating agent.

When handling KAOLIN, basic safety precautions should be followed. Wear protective equipment such as gloves and safety glasses. Store in a dry, cool place to prevent moisture absorption. In case of a spill, use appropriate protective equipment and clean up according to standard procedures. Always refer to the Safety Data Sheet (SDS) for specific handling instructions and emergency procedures.
