This paper presents results of combustion synthesis (Self-Propagating High Temperature Synthesis, SHS) of Si3N4 under nitrogen with argon, hydrogen or ammonia. Higher percentages of α-Si3N4 content were obtained in large size cakes in SHS with hydrogen and ammonia than those with argon. Effect of the auxiliary gases for combustion synthesis of Si3N4 on α phase content, on phase transformation of α-Si3N4 to β-Si3N4 in SHS Si3N4 and on oxygen content in SHS Si3N4 were investigated.
