Abstract

Coarse α-LiALO₂ powder was transferred completely to γ-LiAlO₂ at 900 ℃ for ten hours. Fine γ-LiALO₂ powder was prepared by “chloride” synthesis. MCFC matrix was fabricated by mixing the coarse and fine γ-LiALO₂ powder and by tape cast. The out'put voltage of the cell assembled with the matrix was 0.85 and 0.75 V respectively at 200 and 300 mA/cm ², and power density was about 250 mW/cm². The performance of the matrix fabricated with the mixed powder was obviously more advanced than that of the matrix fabricated with only coarse γ-LiALO₂ powder.
