Transport properties of molybdenum in the high temperature range

Investigations of thermal diffusivity and thermal conductivity of molybdenum (with purity not less than 99.92 weight %) - a prospective standard material for thermal conductivity are carried out within the frames of french-soviet cooperation on ensuring praservation of measurement unity of metal migration properties. Thermal diffusivity is measured by two methods within 300-2200 K temperature range. Heat conductivity is measured by the method of longitudinal heat flux within temperature range of 300-850 K (by the French side) and within the range of 400-2200 K (by the Soviet side). Discussed is the degree of the result coincidence
