Summary

From thirteenth international conferencc on thermal conductivity; Lake Ozark, Missouri, USA (5 Nov 1973). A longitudinal heat flow technique for precise measurement of thermal conductivity, electrical resistivity, and Seebeck coefficient over the temperature range from 80 to 4OO deg K is described. The basis of the technique is the use of a calibrated platinum resistance thermometer to provide in-situ calibrations of specimen thermocouples. The total determinate errors at 273 deg K are plus or minus 0.23% for electrical resistivity, plus or minus 0.49% for thermal conductivity, and plus or minus 0.07 mu v/K for the Seebeck coefficient when Pt wire is used as the reference. Experlmental results on two high-puriiy molybdenum specimens with cross-sectional areas differing by a factor of four are presented to demonstrate the system precision and low level of indeterminate errors.
