China clay, commonly referred to as kaolin, is a natural mineral that is essential across various industries due to its unique properties. With the chemical formula Al2Si2O5(OH)4, this white clay is primarily derived from the kaolinization process, whereby aluminum-silicate minerals undergo natural chemical weathering. It finds its primary applications in the ceramic, paper, cosmetic, and pharmaceutical industries, owing to its substantial strength, whiteness, and heat resistance. In the realm of ceramics, china clay is a fundamental ingredient, used for manufacturing porcelain, fine china, sanitary ware, tiles, and pottery. In the paper industry, it enhances the quality of printed materials by improving opacity, smoothness, and glossy finish. Additionally, in cosmetics, china clay is favored for its oil-absorbing and gentle exfoliating properties, making it ideal for facial masks and powders. With its chemical inertness and resistance to heat, china clay is not only versatile but also safe for various applications. Its production is streamlined through in-situ mining, which allows for easy extraction and refinement to meet industry-specific requirements. This makes china clay an indispensable mineral in the B2B marketplace, offering high quality and much-needed adaptability across multiple sectors.

Country Of Origin: India
China Clay is also known as kaolin & white clay. Primary clay formed by natural kaolinization process.
The chemical formula for china clay used in mineralogy is Al2Si2O5(OH4).
It's primarily used in ceramics, paper manufacturing, paints, and cosmetics, as well as in agriculture and pharmaceuticals.
Here's a more detailed look at its uses:
1. Ceramics:
China clay is a fundamental ingredient in the production of porcelain, fine china, and other ceramics, contributing to its strength, whiteness, and heat resistance.
It's also used in making sanitary ware, tiles, and pottery.
2. Paper:
China clay serves as a filler and coating material in paper production, improving its opacity, smoothness, and printability.
It enhances the quality of printed materials and makes paper more glossy.
3. Cosmetics :
China clay is used in cosmetics for facial masks, powders, and soaps, as it absorbs oil and has gentle exfoliating properties. .
Key Properties and Characteristics:
Composition: Primarily kaolinite (Al2Si2O5(OH)4), a hydrated aluminum silicate.
Formation: Results from the chemical weathering of aluminum-silicate minerals like felspars.
Appearance: White or light-colored, with a fine, powdery texture.
Physical Properties: Brittle, often with a slippery feel, and it becomes plastic when wet. It also emits a distinct clayey odor when breathed upon.
Chemical Properties: Chemically inert and resistant to heat.
Production and Processing:
Mining:
China clay is often mined in situ, meaning it's soft and easily extracted without blasting.
Processing:
Crushing, grinding, and refinement processes may be used to achieve specific particle sizes and purity levels.
