Abstract
A process is disclosed in which a stable aqueous dispersion of a complex alkali metal-aluminium-silicate is prepared by mixing an aqueous solution of alkali metal silicate and an aqueous solution of an aluminium salt in a mixing tube and constraining the solutions to pass through the mixing tube in a generally helical path and under a pressure drop of at least 40 psi. Apparatus for carrying out the process is also disclosed.
