Kaolin clay powder is one of the most widely used industrial minerals in India due to its high whiteness, fine particle size, chemical stability, and cost-effectiveness. It plays a crucial role in improving product quality across industries such as ceramics, paper, paints, rubber, pharmaceuticals, plastics, and construction. At Minerals Bazaar, we supply premium-quality kaolin tailored to meet diverse industrial requirements.
Kaolin clay powder, also known as china clay, is a naturally occurring mineral primarily composed of kaolinite. It is soft, white, and chemically inert, making it suitable for applications where purity, brightness, and consistency are essential. These properties make kaolin an ideal filler, extender, and functional additive.
Kaolin is formed through the natural weathering of aluminum-silicate minerals such as feldspar. After mining, the raw material undergoes refining to remove impurities. The clay is then dried, ground, and classified to achieve uniform particle size and quality suitable for specific industrial applications.
Hydrous Kaolin
Retains natural moisture and is commonly used in paper manufacturing, ceramics, paints, and coatings.
Calcined Kaolin
Produced by heating hydrous kaolin to enhance brightness, hardness, and opacity. It is widely used in rubber, plastics, and high-performance ceramics.
The performance of kaolin depends on the following characteristics:
Kaolinite (Al₂Si₂O₅(OH)₄): Provides plasticity and whiteness
Silica (SiO₂): Improves strength and thermal stability
Alumina (Al₂O₃): Enhances hardness and durability
Fine particle size: Ensures smooth texture and better dispersion
High brightness: Essential for paper, paint, and ceramic products
These properties determine the suitability of kaolin clay powder for industrial use.
Used in porcelain, sanitaryware, and tiles to improve strength, binding, and surface finish.
Enhances brightness, opacity, smoothness, and printability.
Acts as an extender and filler in distemper, emulsion, and decorative paints.
Improves tensile strength, durability, and overall performance.
Used in medicinal powders, ointments, and skincare products due to its absorbent nature.
Improves binding properties in cement, plasters, and mortars.
Enhances heat resistance, strength, and surface quality.
Used as a carrier to improve stability and controlled release of active ingredients.
