Research Abstract

Aluminum nitride (AIN) is a very important ceramics material for nuclear fusion reactor. In this research project, we have aimed to elucidate the irradiation effect of AIN due to nuclear transmutation and displacement damage. In order to attain this goal, before the irradiation, we firstly manufactured an experimental apparatus for production of high purity Al^<15>N ceramics, and then evaluated the various properties of the AIN obtained with isotopic adjustment. We were successful in the production of the AIN ceramics with high thermal conductivity. Physical, optical and thermal properties of the obtained AIN ceramics were investigated before and after irradiation. We carried out the irradiation experimental at RTNS-II, JMTR, JOUYOU, FFTF and HFIR. Furthermore, we established the new experimental thechnique of thermal diffusivity of ceramics by the use of laser flash method. Finally, we indicated the feasibility of laser production of AIN ultra-fine particles for preparation of RF window materials of nuclear fusion reactor.
