Abstract

Measurement of the electrical resistivity of molybdenum in the temperature range 1500 to 2650 K by a subsecond-duration pulse-heating technique is described. The specimens were of the National Bureau of Standards Molybdenum Standard Reference Material 781 for Enthalpy and Heat Capacity. The electrical resistivity of molybdenum in the temperature range 1500 to 2650 K is expressed by the following function (standard deviation = 0.2%):

$$\rho = - 6.7083 + 2.8949{\text{x10}}^{{\text{ - 2}}} T + 5.2985{\text{x10}}^{{\text{ - 7}}} T^2 $$
(1)

where T is in K and ρ is in ΜΩ · cm. The estimated inaccuracy in the electrical resistivity data does not exceed 1%.
