Research Abstract

Several kinds of ceramics are necessary for fusion and fission nuclear reactors.and it is recognized that irradiation responses of various kinds of ceramics are influenced by their crystal structures and atomic bonding natures. However,identification of irradiation-induced crystalline defects and their thermal stabilities is not yet sufficientry understood, and unified mechnism is not obtained. Furthermore, recentry effects of transmuted He are suggested to be associated with structural defects then more complex phenomena occur. In this research, macroscopic length recovery for several kinds of ceramics were precisely observed by means of high-precision dilatometry coupled with mass spectroscopy, and then it was defined that the kinds of irradiation-induced crystalline defects and thermalstabilities, for silicon carbide, silicon nitride and SiAlON polymorphs.
