Abstract It is shown that zirconia is chemically compatible with lithia-stabilized β″-alumina and that incorporation of tetragonal zirconia in the matrix of β″-alumina leads to an improvement in fracture toughness and four-point bend strength without significantly affecting ionic conductivity. Chemical compatibility is demonstrated by reacting α-alumina with sodium zirconate at 1250° C which leads to the formation of β″-alumina and free zirconia. The fracture toughness as measured using the indentation technique is found to increase with increasing crack length.
