Abstract

SrTi1–xZrxO3 (0 ≤ x ≤ 1.0) ceramics were synthesized from powders generated by sol-spray pyrolysis. Crystal symmetry, morphology, and the band gap of the prepared ceramics were investigated as a function of Ti/Zr ratio. Substitution of Zr4+ for Ti4+ in the solid solution markedly effects crystal symmetry and grain growth and results in an increased band gap. Single-phase products with good crystallinity and dense microstructure were obtained after sintering at 1250°C.
