Abstract The Cr2AlC ceramic powder was synthesized by using the molten salt method in carbothermal reduction atmosphere. The orthogonal experiments were designed to investigate the effects of cosolvent dosage, synthesis temperature, raw material ratio and holding time on the productivity of Cr2AlC powder. The optimal synthesis parameters were achieved and then be verified. The results show that synthesis temperature is the most principal factor, then is the cosolvent dosage and holding time, raw material ratio is the last one. The carbothermal reduction atmosphere has the same function of preventing raw material from oxidization with argon atmosphere.
