The effect of Al substitution for Zr on the sinterability of SrZrO3 powders was studied by means of XRD, BET, and SEM. The density of SrZrO3 increased with increasing amount of Al, and the sinterability of SrZrO3 was greatly improved by the substitution. The highest density of 94% was achieved for SrAl0.02Zr0.98O2.99ceramics prepared after calcining at 1300°C and firing at 1600°C for 3 h. The analysis of isothermal shrinkage curves exhibited that the diffusion mechanism changed from grain-boundary to volume diffusion by the formation of oxygen vacancy. The dielectric constant of the present SrZr1-xAlxO3-δ ceramics increased to around 45 from 20 of pure SrZrO3 ceramics in the frequency range 1 kHz to 100 kHz.
