SiO, under ion or electron beam irradiation have been studied using a Kelvin probe that measures work function changes of materials. Surface charging was observed to influence greatly the probe output, which can be explained qualitatively employing a model concerning polarization effect in insulating ceramics due to free charges on their surfaces. It is found that the insulating ceramics could not be studied properly with the Kelvin probe. A probable solution has been presented, i.e., to heat the ceramics, so as to raise their electric conductivities high enough to root out the surface charges

Demonstration power plant (DEMO) reactors require advanced tritium breeders with high tritium breeding ratios (TBRs) and increased stability at high temperatures. Thus, I focused on a solid solution with a new characteristic as a super advanced tritium breeder. Since the atomic radius of Li and Zr is similar, I surveyed the possibility of solid solution for a LiO-TiO-ZrO (LTZO) system. The results show that LTZO pebbles are not a two-phase material but a solid solution. Furthermore, the grain size control of LTZO pebbles is simpler than that of LiTiO pebbles. Although LiTiO pebbles were sintered under vacuum and subsequent 1%H-He atmospheric conditions to obtain the target values, LTZO pebbles 
5 
m grain size were easily sintered under air.
