Abstract

Coarse α_LiALO 2 powder was transferred completely to γ_LiAlO 2 at 900 ℃ for ten hours.Fine γ_LiAlO 2 powder was prepared by “chloride” synthesis. MCFC matrix was fabricated by mixing the coarse and fine γ_LiAlO 2 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/cm 2.The performance of the matrix fabricated with the mixed powder was obviously more advanced than that of the matrix fabricated with only coarse γ_LiAlO 2 powder.
