The formation of cubic molybdenum carbide (α-MoC<SUB>1−<I>x</I></SUB>) by the carbonization of MoO<SUB>3</SUB> with graphite by heating with argon plasma arc was studied. α-MoC<SUB>1−<I>x</I></SUB> including a small amount of hexagoanl η-MoC<SUB>1−<I>x</I></SUB>. was formed. By the carbonization of mixture of MoO<SUB>3</SUB> and TiO<SUB>2</SUB> with graphite, a cubic solid solution of Mo–Ti–C system was formed. Chemical and X-ray analyses showed that the cubic form is defective in carbon content. The density of the cubic form was in agreement with that determined by means of X-ray diffraction. The products were found to be superconductors, the transition temperature varying with composition. The highest transition temperature 11.7 K was obtained for Mo<SUB>0.95</SUB>TiO<SUB>0.05</SUB>C<SUB>0.75</SUB>.
