SLIDING MEMBER, AND BEARING, MOTOR AND DRIVING DEVICE USING SAME
Provided is a sliding member comprising a sintered silicon nitride having silicon nitride crystal grains and grain boundary phases, the sliding member being characterized in that in a 50 µm x 50 µm observation area of an arbitrary cross section or surface of the sintered silicon nitride, a proportion of the number of silicon nitride crystal grains having dislocation defects therein in arbitrary 50 silicon nitride grains showing full contours thereof is 0-10% inclusive. More preferably, said proportion is 0-3% inclusive.
