Conclusions
Measurements have been made on the thermal conductivity and thermal diffusivity for corundum refractories based on hollow granules having apparent densities of 0.3–0.6 g/cm3, as well as foam corundum ones at about 0.5 g/cm3, which cover the range 200–1700°C. A conduction model has been devised that gives a qualitative explanation of the temperature and porosity effects.
