Kaolin (White Clay)

Formula: Al₂Si₂O₅(OH)₄) GOST/CAS: ГОСТ 19608-84 / CAS 1332-58-7

Kaolin is a naturally occurring, fine-grained white clay mineral consisting primarily of kaolinite. It possesses high refractoriness, low plasticity, excellent binding properties, and chemical inertness. Kaolin is highly sought after as a functional filler and pigment. The product enhances the physical and mechanical characteristics of finished goods, improves their optical properties, and optimizes production costs by partially replacing more expensive components.

Applications

Ceramics Production: The primary raw material for manufacturing porcelain, earthenware, electrical insulators, and sanitary ceramics.

Paper Industry: Used as a filler and pigment for paper coating, improving whiteness, smoothness, and overall printability.

Paints and Coatings: Acts as a matting agent and filler in paints, enamels, and primers, improving hiding power and rheological properties.

Rubber and Plastics: Applied as a reinforcing filler for mechanical rubber goods and plastics, increasing their tensile strength and dielectric performance.

Key Advantages

High Whiteness: Ensures excellent optical properties in paint coatings and paper products.

Chemical Inertness: Does not react with most acids and alkalis, ensuring the stability and durability of the final product.

Fine Dispersion: Easily and evenly distributed in mixtures without causing abrasive wear to production equipment.

Cost-Efficiency: Optimizes formulations by reducing the consumption of expensive pigments (such as titanium dioxide).

Storage & Transportation

Store in dry, covered warehouses, reliably protected from moisture.
Transport in closed vehicles to prevent wetting and mechanical contamination of the product.
Unlimited shelf life when stored under appropriate conditions in intact factory packaging.
