Products: China Clay

China Clay is a Hydrated Aluminum Silicate,, which falls under the Kaolinite group of clays is formed by weathering or hydrothermal alteration of felspathic rocks. It has the general formula Al2,(Si2O5) (OH)4. Free Silica (grit) is the most undesirable impurity and is removed during processing by levigation, sedimentation or air-separation. First we collect the samples from various mines which is analysed for composition and physical and chemical properties and its suitability for various applications is then studied. Moreover, sustained availability of the material with no variation from mines is given utmost importance to ensure consistency in final product.
