SILICON NITRIDE SINTERED BODY, WEAR-RESISTANT MEMBER USING SAME, AND METHOD FOR PRODUCING SILICON NITRIDE SINTERED BODY
A silicon nitride sintered body includes a silicon nitride crystal grains and grain boundary phases. Further, when D stands for width of the silicon nitride sintered body before being subjected to surface processing, relations between an average grain diameter dA and an average aspect ratio rA of the silicon nitride crystal grain in a first region from an outermost surface to a depth of 0 to 0.01D and an average grain diameter dB and an average aspect ratio rB of the silicon nitride crystal grain in a second region inside the first region satisfy the inequalities: 0.8≤dA/dB≤1.2; and 0.8≤rA/rB≤1.2.
