Expansion of the temperature range of utilization of SOTM-2150 standard sample of thermal conductivity

The results of additional experimental investigations are used to expand the temperature range of describing the temperature dependence of thermal conductivity coefficient of MChVP (pure vacuum-melted molybdenum) molybdenum previously certified as standard sample of thermal conductivity. New experimental data, obtained in the temperature range from 80 to 320 K, and the results of additional experiments in the hightemperature region enable one to obtain a unified description of polytherm of thermal conductivity in the temperature range from 80 to 2200 K.
