摘要
Results are presented for experimental studies of the thermal conductivity of expanded vermiculite. Tests are performed in an experimental test unit by a steady-state heat flux. Thermal studies are carried out in the range 300-1100 K. It is shown that thermal conductivity increases uniformly with an increase in temperature. The most probable reason for an increase in thermal conductivity is the effect of heat radiation. Results are provided for an approximate second power polynomial.
