Abstract
Using the modern methods of radiative temperature measurements a refined De Senarmont method (1848) is developed. It allows the measurement of the anisotropy ratio k1/k2 of the thermal conductivity in different directions 1,2 of an anisotropic solid at room temperature and above. This transient method is especially suited for poor thermal conductors like polymers and does also provide an estimate of the absolute thermal diffusivity.Keywords
