ABSTRACT:
A method for densifying a fumed metal oxide of Groups III and IV prepared by either a vapor phase oxidation or combustion process is disclosed wherein the metal oxide is mixed with a polar liquid in a high shear mixer, the metal oxide being present in an amount of about 35-50%, to convert it into a granulated material which, when dried, will substantially all pass through a 10 mesh screen. The granulated material may then be calcined preparatory to wet milling to prepare a casting slip, or it may be vitrified directly for molding or drawing in known manner.
