Electrical behaviour of hydridofluorides of potassium-calcium KCaH3-xFx with x = 1, 1.5, 2, 2.5

International audienceThis paper reports the results of the electrical conductivity measurements for KCaH3-xFx series with (x = 1, 1.5, 2, 2.5) in the temperature range 298-503 K. The activation energy of the electrical conductivity for the studied compounds depends on hydrogen amount and Reau's criteria. Differential thermal analysis curves were measured in the same temperature range 298-503 K. Possible correspondence between preferential order given by X-ray diffraction, thermal behaviour and electrical properties are discussed
