✦ Synopsis

This paper reports the results of a study of high purity chromium single crystal electric resistivity. The chromium single crystal used in this study was produced from commercially available 5N electrolytic chromium. The gaseous impurity level improved during single crystal production. The crystal structure was investigated by means of the Laue method and the sample was confirmed to be a single crystal. The single crystal was carefully cut into a rectangular bar in preparation for the resistivity measurement. The electrical resistivity was measured for the [100], [111] and [110] crystal orientations utilizing the four-probe method. One measurement indicated 1.08 Â 10 ± ±7 Wm at [100] at 20 C; that is less than the previously reported pure chromium resistivity of 1.25 Â 10 ± ±7 Wm.
