| titleOfInvention | Alumina ceramic product for sliding part and method of manufacturing the same |
| abstract | (57) [Problem] To determine the optimal alumina ceramic structure for obtaining a good surface roughness of an alumina ceramic product for a sliding portion, and to establish a manufacturing technique for realizing the structure. SOLUTION: The purity is 99.9% or more and the relative density is 99%. %, And the maximum value of the maximum circumscribed circle diameter of the alumina particles in 20 visual fields of 20 μm × 15 μm of the sintered body observed at 5000 × using a scanning electron microscope is 5%. Alumina ceramic product for a sliding part characterized by having a mean particle size of 1.4 μm or less, wherein a single crystal alumina particle is used as a raw material, and MgO is used as a sintering aid. Less than 1000 ppm (excluding 0 ppm), Sintering at 1250-1590 ° C., or using single crystal or polycrystalline alumina particles as raw materials, It is manufactured by sintering at 590 ° C and then hot isostatic pressing at 1200 to 1550 ° C. |
