摘要
A sintered silicon nitride member formed predominantly of silicon nitride, wherein at least a surface of the sintered member has a lightness VS of 3.0 to 9.0 and/or a chroma CS of not greater than 3.0. The sintered member facilitates identification of defects such as pore and/or foreign matter of different color formed at the surface and is capable of enhancing inspection accuracy. Also disclosed is a sintered silicon nitride member in the form of a ceramic ball having such a lightness on its surface.
