Calcined Kaolin Powder Chemical Name: Aluminium Silicate (Al2O3, 2SiO2, 2H2O) Calcined Kaolin is naturally occurring hydrated Aluminium Silicate. It mainly has oil absorbing properties, reduced shine and translucent properties. It also provides hiding effect and reduces the usage of TiO2 to a great extent. Chemical/Typical Composition of Calcined Clay Parameters - Calcined Clay SiO2 - 48% Al2O3 - 41% Loss on Ignition - Below 1% Specific Gravity - 2.41 Oil Absorption - 42 pH - 6.5 to 7 Industrial Applications Paper Industry, Paint Industry, Rubber Industry, Plastics Industry, Ceramics , White Cement & Etc.
