ABSTRACT:
A method of densifying a fumed metal oxide is disclosed wherein the metal oxide is converted to a flowable sol and then dried to form a fragmented solid which is calcined. The calcined oxide may be wet milled to provide a slip for casting articles such as fused silica crucibles used in melting silicon. The method also permits the production of very refractory fused glass compositions from fumed metal oxides at temperatures substantially below those required where a melting step is employed.
