Sintered silicon nitride and wear-resistant member using same
Provided are: a silicon nitride sintered body having improved wear resistance; and a wear-resistant member using the silicon nitride sintered body. A silicon nitride sintered body according to an embodiment is provided with silicon nitride crystal particles and a grain boundary phase. In a 20 [mu] m * 20 [mu] m region of an arbitrary cross section, the average value of the solid-solution oxygen content of the silicon nitride crystal particles is 0.2 wt% or more. In a 50 [mu] m * 50 [mu] m region of an arbitrary cross section, the average of the major axes of the silicon nitride crystal particles is 0.1 [mu] m or more and 10 [mu] m or less, and the average of the aspect ratios of the silicon nitride crystal particles is 1.5 or more and 10 or less.
提供提高了耐磨性的氮化硅烧结体及使用了其的耐磨性构件。实施方式的氮化硅烧结体具备氮化硅结晶粒子及晶界相。在任意的截面的20μm×20μm的区域中，上述氮化硅结晶粒子的固溶氧量的平均值为0.2wt％以上。在任意的截面的50μm×50μm的区域中，上述氮化硅结晶粒子的长径的平均值为0.1μm以上且10μm以下，上述氮化硅结晶粒子的长宽比的平均值为1.5以上且10以下。
