摘要

In-doped SrTiO₃ with B-site deficiency was synthesised by sol-gel method. The effects of B-site deficiency on the weight loss, phase, microstructure and electrical properties of Sr(Ti_0.9In_0.1)_1-xO_3-δ (x = 0, 0.02 and 0.04) samples are investigated. The solid solution is formed at 1016 °C. Sr(Ti_0.9In_0.1)_1-xO_3-δ powders sintered at 1400 °C for 5 h in air exhibit a single-phase cubic perovskite structure. The total electrical conductivity initially increases and then decreases with further increase in the temperature. The conductivity of Sr(Ti_0.9In_0.1)_0.96O_3-δ reaches the maximum value of 0.0158 S cm^-1 at 400 °C.
