Thermal behavior of the KSbMoO6 ionic conductive ceramic

A thermoelectric study of the KSbMoO6 (KSM) ionic conductive ceramic was do ne. In the study, the variations of permittivity and dielectric loss with t emperature were recorded. Four fundamental effects were detected: two in th e range 50 - 200 degrees C which are attributed to the dehydration of the m aterial, and two related to phase transformations above 200 degrees C. The enthalpies Delta H involved in the processes are reported. The thermal beha vior was also studied by Differential Scanning Calorimetry (DSC) and Thermo gravimetric Analysis (TGA). A coincidence between the thermal and the elect rical technique was observed. (C) 1999 Elsevier Science S.A. All rights res erved.
