Thermal conductivity of CaO-B2O3 system as functions of temperature including glass transition
Source abstract
Abstract
The study aims to investigate the possible effect of glass transition firstly on the thermal conductivity of the CaO-B 2O 3 system. The addition of CaO was varied in the range of 0 to 40 mass %. The transient hot-wire method, transient hot-strip method, laser flash method and the thermoreflectance method were applied for the investigation in the temperature range of 298 K to 1175 K. Positive temperature dependence was found for the 38mass %CaO-B 2O 3 sample, which is the same as reported for B 2O 3 . However, slopes of the temperature dependence change just above the respective glass transition temperature. The addition of CaO to B 2O 3 leads to the increase of thermal conductivity. The study discusses the possible structural change of B 2O 3.
