In this study, the influence of oxidation of starting powders on densification was investigated. Oxidation of SiC powders, prior to liquid phase sintering, increased the oxygen content and decreased the carbon content remarkably, and led to higher sintered density for both alpha- and beta-Sic. Higher sintered density was attributed to the formation of liquid at lower temperatures and the suppression of reactions between the free C and oxide additives.
