Ceramic Ball Material, Method For Manufacturing Ceramic Ball Using Same, And Ceramic Ball
A ceramic ball material according to the present embodiment includes a spherical portion, and a band-shaped portion formed over a circumference of a surface of the spherical portion. The band-shaped portion has a width in a range of 0.5 mm or more and 4.0 mm or less, both shoulders of which are provided with an R section having a radius of curvature of 0.02 mm or more. Any one of aluminum oxide, silicon nitride, boron nitride, and zirconium oxide is used as the ceramic.
