ALTHOUGH kaolin minerals appear to be formed in Nature under acidic conditions at relatively low temperatures and low water-vapour pressures, their synthesis in the laboratory under similar conditions has been found exceptionally difficult. It appears that a proper choice of many variables is essential. In previous investigations1,2, individual kaolinite crystals have been obtained by ageing mixed alumina and silica gels for 2 months at 100° C. and under pH. conditions around 4.5, but the… CONTINUE READING
