The vanadium carbide prepared from vanadium trioxide by vacuum carbothermal reduction was studied. The variation of density of vanadium carbide with experimental conditions was also studied. The additive for strengthening the density of vanadium carbide product was found. The results showed that the reaction temperature, Additives are the main factors affecting the density of vanadium carbide products, the reaction time has a certain impact on product density. The results also show that iron-containing compounds can effectively increase product density
