Outline of Final Research Achievements

(1) The Pb-Li alloys with various Li concentration were fabricated with the small metal grains of Li and Pb. Small metal grains of Li and Pb should be well mixed before the heating and the melting to prevent the formation of Li rich alloy by the segregation of Li. The chemical behaviors of non-metal impurities in the alloys are investigated by means of temperature programmed desorption method.(2) The electrical characteristics of Y2O3 and ZrO2 in a static Pb were successfully obtained by an electrochemical impedance spectroscopy. The results indicated that the in-situ analysis of the formation and the growth of the oxide layers in a liquid metal can be done by the EIS method. (3) The solid electrolyte sensor and the specimen of pre-oxidized zirconium (Zr) were simultaneously immersed to liquid Pb at 698-898K. The responses of the sensor and the EIS were successfully obtained, and these signals indicated that the Zr oxide layer is chemically stable in liquid Pb.
