About Kaolin
Kaolin (theoretical formula: Al₂[(OH)₄/Si₂O₅]) is a non-metallic mineral — a clay and claystone mainly composed of kaolinite-group clay minerals. It is white and fine, also known as "white clay" or "porcelain clay". It is named after Gaoling Village in Jingdezhen, Jiangxi Province.
Pure kaolin is white, fine, soft and earthy, with good plasticity and refractoriness. It is an essential ingredient in the manufacture of china and porcelain and is widely used in paper, rubber, paint and many other products.
In its natural state, kaolin is a white, soft powder consisting principally of kaolinite. Under the electron microscope, kaolinite appears as roughly hexagonal, platy crystals ranging from about 0.1 to 10 micrometres or larger. Approximately 40% of kaolin produced is used in paper filling and coating. It is also used extensively in ceramics, refractories, rubber reinforcement, paints, adhesives, inks, organic plastics and cosmetics.
Calcined Kaolin & Surface Modification
Calcined kaolin is made from natural kaolin through calcination and dehydration. It features high whiteness, large surface area, insulation and thermal stability. It has excellent chemical corrosion resistance, solvent resistance, acid and alkali resistance, and good reinforcing and processing performance — widely used in coatings, paints, papermaking, rubber, plastics, cables, ceramics and other industries.
Calcination temperature is a key factor determining the application of the final product:
- Low temperature (600–1000°C): High-activity kaolin, used in molecular sieves, aluminum salt chemicals, and functional plastic/rubber materials.
- Medium temperature (1000–1200°C): High whiteness and opacity, used in papermaking and coatings, replacing titanium dioxide as a structural pigment.
- High temperature (above 1200°C): Forms mullite and cordierite, used in foundry sand, high-grade refractories and special ceramics.
Surface modification changes the surface physicochemical properties of calcined kaolin to improve its affinity and dispersion in organic polymer materials, enhancing product performance, increasing filling quantity, and reducing costs. Silane coupling agents are most commonly used, with a typical dosage of 0.3%–1.2%. The modification process involves heating the calcined kaolin to about 100°C under high-speed dynamic conditions, adding hydrolyzed silane coupling agent or compound modifier (preferably atomized), maintaining reaction temperature within 120°C for 3–5 minutes.
Common surface modification equipment includes high-speed kneading machines, continuous modification machines, and high-frequency vibration mills. The selection of equipment should be based on the surface modification mechanism and process to meet technical requirements.
Commitment to the Future
Looking ahead, Shanxi Jufeng New Material Technology Co., Ltd. will continue to uphold its original aspiration, increase investment in scientific research and innovation, and provide high-performance, eco-friendly kaolin products to customers worldwide.
