Abstract

Silicon carbide (SiQ is an important material in industry and defense due to its favorable mechanical, chemical and thermal properties. In the presence of oxygen, silicon carbide powders will react to form a thin oxide layer (SiOi) on their surfaces. This oxide layer can inhibit the densification of solid-state sintered silicon carbide and result in undesirable effects on the dense microstructure. In this study, commercially available silicon carbide powders with varying levels of oxygen content were densified via spark plasma sintering (SPS) with boron carbide and carbon additives. Several silicon carbide samples with varying microstructures were produced and the densified samples were characterized to determine the effect of the starting powder's oxygen content on their microstructure and mechanical properties.
