Kaolin can be used as raw material to synthesize zeolites. After the first reported synthesis of zeolite-A from kaolin in 1988 ( Costa et al., 1988 ), continuous efforts have been made to prepare various types of zeolites, such as zeolite-13X, zeolite-β, and ZSM-5 ( Lucas et al., 1992, Wang et al., 2007, Shen et al., 2009 ), which exhibit ...

Kaoline. Definition of the term kaolin. Kaolin is a natural mineral raw material and belongs to the large group of silicates. Kaolin is a weathering product of feldspar and contains the mineral kaolinite, an aluminium silicate or aluminosilicate (chemical formula: Al2O3-2SiO2-2H2O). It is a rock that usually occurs in loose, white masses.

High alkalinity is necessary to the destruction of raw material (Hua and van Deventer, 2003). In other words, too much water will reduce the geopolymerisation rate at period I for its dilution effect. Download : Download full-size image; Fig. 3.

Kaolin is pure clay mineral, having a fired chemistry of 1 molar part Al 2 O 3 and 2 parts SiO 2. However the raw clay crystals are hydrated, having 12% crystal-bound water. This is the secret to their plasticity. Calcining the material removes that water and destroys the plasticity. Calcined kaolin is not commonly used in traditional ceramics ...
