Abstract

The ion conductivity of the salts [(C₄H₉)₄N]BF₄ and [(C₄H₉)₄N]Br was studied in vacuum at temperatures from room temperature to 190 and 135°C, respectively. The salts have phase transitions to disordered high-temperature phases accompanied by an increase in conductivity. [(C₄H₉)₄N]Br has higher conductivity than [(C₄H₉)₄N]BF₄. As the conductivity decreases with the increasing size of the anion, the BF₄ ^– and Br^– anions are the most probable current carriers in the salts.
