What's the difference between kaolin and kaolin?
(kaolin) also called Gaoling reservoir soil, white clay, clay soil, Yang (porelain clay). The main component is aluminum silicate hydrate (A12O3.2SiO2.2H2O). The color white or grayish, a hexagonal flaky crystal, the relative density is 2.54 ~ 2.60, oil content is 30% ~ 50%. kaolin pH value is generally 4 ~ 5. A weak acid.
Clay resources are mainly distributed in the Hengshan area. The main ore bearing horizon is the upper Cretaceous silty clay, the third century, eluvial slope area, Pleistocene Qi mouth group silty clay. The Quaternary deposits (points) sampling analysis: silica containing 65.18-71.86%, three 15.02-17.99% 3.27-6.61% two aluminum oxide, ferric oxide, calcium oxide 0.75-1.68%, Magnesium Oxide 0.89-2.07%, LOI 4.19-6.20%.
Effects: 1., firing pottery,.2. firing pottery or coarse porcelain kaolinRefers to the clay containing iron and gray white, red brown, purple and other colors, with good plasticity of the clay mineral composition of montmorillonite, kaolin.. clay is mainly used as exterior wall tiles, pottery, burning out.
