title: Activation Energy of Direct-Current Electrical Conductivity of Ice with HF and NH3 Added.
abstract: The activation energies of ice with varying amounts of impurities added were investigated with sintered platinum electrodes. For both types of impurities the activation energy was minimum at a concentration of 10(-4)M. The experimental arrangement and possible reasons for the existence of a minimum in activation energy are discussed.
