Abstract
The difficulties of measuring the thermoelectric power of ice by the electrode method are discussed and there follows a description of a new induction method requiring no electrodes. Measurements with this technique on single crystals of rather pure ice at temperatures near -20°c yield a value of dV/dT=−2·3±0·3 mv/°c compared with a theoretical value of -1·9 mv/°c. The same method is employed to measure potential differences developed between two halves of a polycrystalline ice specimen doped with different concentrations of HF and NH3. Potential differences of 30–40 mv are produced by tenfold changes in concentration of impurity and these measurements are in fair agreement with calculations made on the basis of Jaccard's theory.Keywords
