SILICON NITRIDE SINTERED BODY AND WEAR-RESISTANT MEMBER USING SAME
A silicon nitride sintered body (1) having improved wear resistance and a wear-resistant member using the silicon nitride sintered body are provided. A silicon nitride sintered body (1) according to an embodiment includes silicon nitride crystal grains (2) and a grain boundary phase (3). An average value of solid solution oxygen amounts of the silicon nitride crystal grains (2) in a 20 µm×20 µm region at any cross section is not less than 0.2 wt%. In a 50 µm×50 µm region at any cross section, an average value of major diameters of the silicon nitride crystal grains (2) is not less than 0.1 µm and not more than 10 µm, and an average value of aspect ratios of the silicon nitride crystal grains (2) is not less than 1.5 and not more than 10.
