Kaolin (China Clay)

Specifications Products : Hydrous, Water Washed, Classified Use : Industrial Use Color : White to Super White Form : Lumps, Powder, Noodles Packing Type : Plastic Bags / Jumbo Bags Packing Size : 25kgs/50kgs/ 1000kgs Kaolin is a hydrated aluminium silicate crystalline mineral formed over many millions of years by the hydrothermal decomposition of granite rocks. It is a white soft mineral composed primarily Kaolinite mineral having chemical composition of Al2O3.2SiO2.2H2O with minor amounts of quartz, feldspar and sheet silicate minerals (mica, illite, smectite). Hard and soft clays are characterized by its fine particle size, platy or lamellar particle shape and chemically inertness. Clays having fine particle size are described as hard clay. Phyllosilicates being a sub group of silicate minerals that has typically less than 2um in diameter. The combination of platy shape and fine particle size results in improved processibility, improved reinforcement, tensile strength, abrasion and tera strength. After mining the above mineral ore is dressed, dried, pulverized, air-floated, water washed (levitated), calcined and surface modified. As per the application the grades are selected by the end user. The processing techniques at PEEKAY MINERALS ensures consistent quality, control of top-cut and average particle size and freedom from impurities at pocket friendly costs. Application & Features: Ceramics: China Clay is an essential constituent in Ceramics. It is used by almost manufacturer worldwide in Electrical porcelain, Fine China & dinnerware, Floor and Wall Tile, Roof Tile, Pottery, Sanitary ware, Tableware and other engineering products. The properties important for the use of China Clay in Ceramics are Plastic Properties, Drying properties, Firing properties, Firing Color, Electrical properties such as conductivity, dielectric content etc. Our clay permits product to be easily deformed under stress without rupturing and retains shape produced when stress is removed. Due to low water of plasticity, it does not require intense forming pressure to withstand handling/drying and the Green Strength is better. The Firing properties are excellent to produce super white finish. The processed clay is free from grits and all metallic impurities. The particle size is very low and even which keeps drying shrinkage in desired parameters.
