    摘要： The present invention provides a rotor, a shaft and a sample holder for a centrifugal sintering system. More particularly, the present invention relates to a ceramic member for a centrifugal sintering system which is a member consisting of a rotor, a shaft and a sample holder for use in a centrifugal sintering system imparting a centrifugal force field and a temperature field to a molded body of ceramics or metal powder or a ceramic precursor film wherein the rotor for turning the sample holder, the shaft and the sample holder are composed of ceramics. In a particular embodiment of the ceramic member, the rotor which turns the sample holder is composed of conductive silicon carbide ceramics and the rotor alone is selectively caused to self heat by induction heating means to indirectly heat the sample. In a further embodiment of the ceramic member, the sample holder is composed of a material with a large dielectric loss and the sample holder alone is selectively heated using dielectric heating means to indirectly heat the sample.

    摘要： When a sintered body of ceramic is shot-blasted at normal temperatures to plastically deform the crystal structure of the shot-blasted surface to apply residual stress and is heat-treated to recrystallize fine cracks, dislocated cells in the grain boundary are formed, crystals are finely divided, and the fracture toughness is significantly improved. When the sintered body of ceramic is a thin product, an effective toughening can be attained by shot blasting both the front and back sides. After heat treatment, mechanical strength is significantly improved by removing a part of the modified surface layer by an abrasion treatment.
