Research Abstract

This work succeeded in the identification of the position of the Ba ion in a Ba substitution sample of La_<10>Si_6O_<27>. Furthermore, these works succeeded for generation examination with an oxide electrode to La_<10>Si_6O_<27> for the first time and also succeeded in obtain higher power density in the case of Pt electrode.
