Abstract

Open porous materials of higher strength and higher porosity were produced by a hot isostatic process (HIP). A grinding wheel of fused alumina grain with powdered frit for bridge is discussed as an example. The samples were directly heated to a normal sintering temperature under HIPping conditions. The HIPped products were characterized by higher bending strength in spite of having more open porosity than the normally sintered ones.
