Title: Ceramic ball for bearing and ceramic ball bearing using the same
Inventor: NIWA TOMONORI
IPC: H01B1/14
Filed: 2000-04-12
Abstract: PROBLEM TO BE SOLVED: To provide a silicon nitride-based sintered compact having improved wear resistance and effectively suppressed dispersion. SOLUTION: Electrification of a bearing ball 43 is effectively prevented or suppressed by constituting at least a portion of the constitutitve ceramic with an conductive inorganic compound and imparting appropriate electroconductivity to the ceramic.
