Dense compacts consisting of 40 vol.% Al{sub 2}O{sub 3}-60 vol.% 3 mol% Y{sub 2}O{sub 3}-stabilized ZrO{sub 2} (YSZ) were joined with an interlayer of 50 vol.% Al{sub 2}O{sub 3}-50 vol.% YSZ. A joint was also made at 1200 {sup o}C with an interlayer that was 50 vol.% Al{sub 2}O{sub 3}-50 vol.% ZrO{sub 2}, in which the average particle size of both powders was {<=}20 nm. The joint materials were applied by aerosol spraying, and thus the technique is suitable for commercial application. Superplastic deformation at 1200--1350 {sup o}C required {<=}2 h to form fully dense joints in which minimal grain growth occurred. Virtually perfect joints were also made with various other ratios of Al{sub 2}O{sub 3}-YSZ.
