China-Clay-Powder-vs-Industrial-Minerals
                     China Clay Powder vs. 
Industrial Minerals
Industrial minerals are essential for manufacturing. Choosing the 
right mineral is crucial for product quality and efficiency.
Kaolin China Clay: Properties
Adaptable Mineral Key Characteristics
Weathering of feldspar rocks creates china clay. • Fine to ultrafine particle size
• Chemical stability across temperatures and pH
• Natural purity for food and pharma
• Opacity and gloss for paper coating
Industrial Uses of Kaolin
Paper Coating Ceramic Production
Enhances surface finish and printing. Strength and whiteness in finished products.
Paint Manufacturing Pharmaceuticals
Opacity and durability in paints. Purity and absorption properties.
Comparing Kaolin to Calcium Carbonate
Calcium Carbonate Key Differences
• Rhombohedral crystal structure • Particle size distribution
• Alkaline nature • Light scattering abilities
• Superior light scattering • Brightness value
• High brightness value • pH buffering capabilities
