Method of investigation and experimental device for measuring the coefficient of thermal conductivity of refractory compounds
Annotation
A new axial method is proposed to determine the thermal conductivity coefficient of solids at temperatures above $1000^{\circ}$ C with the use of internal heating of specimens by an electric current and with experimental determination of the heat flux from the side surface of the working section of the specimen. This method can be used to investigate the thermal conductivity of materials with unknown or unstable radiative surface characteristics, and also when it is necessary to conduct experiments not only in a vacuum but also in various gaseous environments. The experimental device is described.
