SINTERED CERAMIC, SLIDE PART THEREFROM, AND PROCESS FOR PRODUCING SINTERED CERAMIC

摘要

It is an object of the invention to provide a ceramic sintered body that has a dense structure and minimal cracking and that exhibits excellent sliding properties even in a non-lubricated state, as well as a process for its production and sliding parts that employ the same. According to a preferred mode, the sintered body of the invention comprises silicon carbide as the parent material and further contains a solid lubricant A with a mean particle size of no greater than 5 µm and a solid lubricant B with a mean particle size of 10-70 µm.
