Abstract

A process for the semicontinuous production of zeolite A of constant and homogeneous quality, which process comprises mixing a solution of sodium aluminate and a solution of sodium silicate instantaneously and continuously in a container and in such a manner that the average retention time in the container is from 30 seconds to 20 minutes thereby to form a gel which is subsequently crystallised in discontinuous fashion. Zeolite A prepared by the process has narrow particle size distribution with range 1-10 microns and ion exchange capacity greater than 110 mg Ca<2+>/g dry product.
