ABSTRACT:
Amorphous silica prepared by the gel route requires washing to remove electrolyte. The gel is formed into small particles by shearing and then washed while being transported by water through stages which separate larger size material. The washing is more rapid than conventional methods and allows the ageing steps to be decoupled from the wash stage.
