Notes:
A device for measuring electrical resistivity as a function of temperature using unsoldered, sharp, and independent contacts has been developed. The probes are fixed on fine ceramic tubes, which are actuated by pressure-sensitive springs. The ceramic tubes are guided by metallic struts that also serve as thermal screens. The device is placed in an enclosure where a primary vacuum is established and introduce a neutral, reducing, or oxidizing gas. Measurement can be performed continually between 86 and 700 K. Materials having resistivities in the 10−8–106 Ω m range have been characterized even when they present resistivity jumps of many orders of magnitude.
