The effect of structural changes on dc ionic conductivity — from room temperature to the melting point at atmospheric pressure — of rubidium nitrate single crystals grown by the slow evaporation method is presented. The anomalous variation of conductivity at structural phase transition points is interpreted on the basis of the unit cell dimensions. Also an attempt is made to remove the ambiguity of room temperature structure.
