The results show that content of the additive and the sintering temperature play an important role on the materials properties, TiB2-Si3N4-BN composite is of better properties at sintering temperature 2073K with the additive of 1wt%.

• 研究结果表明:掺加剂Si3N4含量和烧结温度对材料的性能有显著的影响；在烧结温度2073K；Si3N4掺加量为1%25(质量分数)时复合材料的相对致密度达94.；52%25；抗弯强度达138MPa。 烧结温度过低、Si3N4相的掺加过多会导致材料力学性能下降。
