a process for forming plastic inorganic agglomerates from which inorganic catalysts or adsorbent bodies can be formed is disclosed . the process involves dispersing a portion of said inorganic material as surface hydrated noncolloidal sized dry particles in a water - immiscible solvent ; titrating the dispersion with a controlled quantity of an aqueous phase in the presence of colloidal sized particles of the same or different inorganic material while mixing until a hydrous plastic agglomerate forms ; and separating said hydrous plastic agglomerate from said water - immiscible solvent .
