The synthesis of crystals of silver oxide phases based on molybdenum, investigation of their structure and properties

The electrical conductivity of triple and double molybdates in the temperature range from 200 to 550 0 C was studied. It was shown that the studied ceramic samples of molybdates possess mixed electronic - ionic conductivity with predominant ionic component at high temperatures of the experiment. Electrical properties of triple molybdates are related to their structural features. In structures Me 5(Li 1/3Hf 5/3)(MoO 4) 6 and Me 3LiHf 2(MoO 4) 6 there are extensive channels in which ions can migrate freely. The value of specific electric conductivity and the activation energy E a conductivity of studied molybdates allow to refer them to the category of solid electrolytes.
