    Kaolin (Kaolin) is a non-metallic minerals are formed by the weathering process of phenpat mainly octodaz and Anbit. Weathering process is known as kaolin chemical process.
    Kaolin Chemical composition:
    - Chemical formula: Al2O3.2SiO2.2H2O
    - Composition theory: Al2O3: 39.48%; SiO2: 46.6%; H2O: 13.92%
    - Density: 2.57 to 2.61
    - Hardness: 1 to 2.5
    Particle size (measured by electron microscope): Long Width: 0.1 - 1. thickness of about 0.02 to 0.1 in the sense of Vicnatski, is acidic aluminum - silicon has the formula: H2Al2SiO8H2O mixer with water, kaolin slurry turns into a paste, flexible format lake, diluting to diffuse in H2O.

    During the weathering process, due to the impact of CO2 and H2O Al2O3 and SiO2 link between not being broken and very sustainable, kaolin particles so high hydrolysis resistant, insoluble in water and sediments into mine and SiO2. For phenpat alkaline, besides SiO2 and CaCO3 longer (if the environmental pH less than 7 are weathered slowly resolution CaCO3 for CaO and CO2. The CO2 that is so essential to continue weathering agents phenpat).
    Kaolin applications: Used in the following areas:
    Role: kaolin have been found to increase the viscosity and coating kaolin blur to smooth, uniform particle size right, 5μm particle size ≤58% ÷ 2.4. No and alkalis and acids in the free state, the permeability oil 46.5 ÷ 59cm3 / 100g ..
