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.

Method of toughening and modifying ceramic and ceramic products

A method and an apparatus for sintering a compact of particulate material for a ceramic or of particles of a metal, or a ceramic precursor film, wherein the sintering is performed by heating and burning the compact or the ceramic precursor film while applying centrifugal force to the compact or the ceramic precursor film.
