Diffusion and creep of Sr3(Ca1.18Nb1.82)O9−δ mixed Perovskite fabricated by melt processing

Compressive creep tests of Sr3(Ca1.18Nb1.82)O9-delta mixed Perovskite fabricated by melt processing were conducted in Ar and air to determine the deformation rate and to estimate the diffusion coefficient. At 1300-1350 deg C, the steady-state strain rate (epsilon{dot above}) could be expressed as
