Abstract

The technology for research of thermal conductivity of different materials is offered. It consists of experimental determination of one-dimensional temperature fields in heat-receivers (samples with thermal sensors) from a researched materials and use of these fields for the solving of inverse problems of heat conductivity. Investigation of materials with low (0.6 Wm−1K−1) and high (160 Wm−1K−1) thermal conductivity by the application of offered technology to research an influence of different factors on temperature dependence of thermal conductivity is considered.
