摘要： Poorly or partly crystalline alkali metal aluminosilicate materials having stuffed silica polymorph related-structures in which the aluminium is at least predominantly tetrahedrally coordinated and cation exchange capacities at room temperature of at least 1 meq 100g-1 in aqueous solution. The materials are produced by reacting an aluminosilicate, or a combination of aluminium oxide-containing and silicon oxide-containing compounds, with an alkali oxide-containing reagent. Preferably the reaction is a solid state reaction. Specific surfaces of the material are likely to be less than 45 m2g-1. The preferred aluminosilicate reactants are kaolin group minerals.
