Abstract
Thermal, dielectric, and electron transport properties of dihydrated and anhydrous perrhenates of strontium, barium, cadmium, and lead have been investigated. The DTA of anhydrousM[ReO4]2 (M =Sr, Ba, Cd) compounds exhibit three reversible phase transitions with considerable thermal hysterisis for the first phase transformation. A single reversible phase transition occurs for Pb[ReO4]2. The parent phases of Ba[ReO4]2, Pb[ReO4]2, and Cd[ReO4]2 behave as semiconductors at elevated temperatures. The dielectric constants measured for Sr[ReO4]2 in the temperature range 30 to -160°C give a broad inflection between -40 and -70°C, which probably indicates a phase transition.
