Abstract

In this study, the electrolyte matrix was reinforced by metal wire mesh which has a thickness in the range of 0.30-0.33 mm. Both pure LiAlO2 matrix green sheet and the matrix reinforced by metal mesh were prepared by tape casting and hot pressing methods, respectively. Mechanical properties and resistance against cracking of each matrix samples were investigated in 650 °C by differential pressure and single cell test. When applying both differential pressure and single cell test in the reinforced matrix, N2 cross-over percentage was maintained in 0.1-0.9% constantly. In conclusion, metal wire mesh is a good additive to increase mechanical strength and durability of ceramic composites.
