Abstract

A method of preparing zeolites by hydrothermal crystallisation of an alumino-silicate gel produced by combining solutions of sources of silica, alumina and alkali metal in such a way that a completely dispersed gel of creamy translucent appearance and no visible gel particles is produced. Control of the viscosity of the combining solutions is illustrated as achieving such a result.
