Abstract

Data are presented on the thermal e.m.f. against copper of six single crystal wires of zinc, of which the orientations of the main crystallographic axis with respect to the wire axis, range from 11.4° to 90°. The temperature interval is from -182° to 475° C. From the data are calculated the thermo-electric power, Peltier coefficient, and difference of the Thomson coefficients for Zn against Zn. The data also provide a test for the Voigt-Thomson law for the variation of the thermo-electric power with crystal orientation. The law is verified for the low temperatures, but the deviations at the high temperatures (300° - 400°) are greater than the experimental errors are thought to be.
