Choudhary, B. Singh] Te modified barium stannates BaSn1−x Te x O3 (x=0-15mol%) provides an interesting result (i.e., ferroelectric phase transition) above room temperature. As we increase concentration of Te, dielectric anomalies (dielectric constant and loss) increases but Curie temperature (T c) shifted towards lower temperature side. Impedance analysis indicates the existence of both grain and grain boundary resistance nears the Curie temperature (∼225°C-275°C). At elevated temperature materials show a typically semiconducting nature (i.e., Negative temperature coefficient of resistance (NTCR)).
