<正>According to the relational thermodynamic data,a phase diagram of Al_2O_3-ZrSiO_4-C-N_2 system was presented.Then,by using fused corundum,alumina micro powder,zircon and carbon black as raw materials,β'-SiAlON/ZrN/Al_2O_3 composite materials were prepared by nitridation reaction sintering process.The influence of sintering temperature on phase composition of the synthesized composite materials was investigated by X-ray powder diffraction,and the formation process of the composite materials was also analyzed in detail.The results indicated that theβ'-SiAlON/ZrN/Al_2O_3 composite materials could be prepared at 1773 K by nitridation reaction sintering process.The formation process of the composite materials included the decomposition of zircon,the formation of Si_2N_2O and Si_3N_4,the formation of O'-SiAlON andβ'-SiAlON as well as the nitridation process of Zro_2.
