METHOD OF MEASURING TEMPERATURE DEPENDENCE OF THERMAL CONDUCTIVITY COEFFICIENT OF ELECTROCONDUCTIVE MATERIALS AT HIGH TEMPERATURES

摘要

FIELD: measuring equipment.;SUBSTANCE: invention relates to measurement equipment, in particular – to measurements of thermophysical properties of materials, which are used in high temperatures, where properties have pronounced dependence on temperature. Substance of invention consists in fact that to obtain temperature dependence of thermal conductivity temperature coefficient of heat conductivity of analyzed sample is measured, using Thomson effect, and sought heat conductivity is calculated.;EFFECT: increase in the measurements accuracy.;1 cl, 2 dwg
