ShareSENSITIVE METHOD FOR DETERMINING THERMAL CONDUCTIVITY OF PURE METALS AT LOW TEMPERATURES.
Author(s) : FONTEYN D., PITSI G.
Type of article: Article
Summary
MEASUREMENTS OF THE THERMAL CONDUCTIVITY OF PURE METAL SAMPLES AT LOW TEMPERATURES POSE SPECIAL PROBLEMS BECAUSE OF THE HIGH CONDUCTIVITY. A NEW SENSITIVE METHOD IS DESCRIBED. THIS TECHNIQUE CONSISTS OF USING A CALIBRATED GOLD-IRON/NIOBIUM-TITANIUM THERMOCOUPLE AS A DIFFERENTIAL THERMOMETER IN CONJUNCTION WITH A SQUID. SPECIAL ATTENTION IS PAID TO THE CALIBRATION OF THE PRIMARY THERMOMETER. A SENSITIVITY OF 1 MICROK IS REACHED FOR MEASURING TEMPERATURE DIFFERENCES.
