Thermal conductivity of ceramics

Thermal conductivity of ceramics depends on phase composition and spatial arrangement of the phases. It is greatly affected by porosity. The pores reduce conductivity at low temperatures unless they facilitate convective heat transfer. Heal transfer in pores by radiation becomes increasingly effective with increasing tempera-...

Another important thermal property dealt with in Sec. 13.6 is thermal conductivity. It is the low thermal conductivity of ceramics, together with their chemical inertness and oxidation resistance, that renders them as a class of materials uniquely qualified to play an extremely demanding and critical role during metal smelting and refining. Many ceramics such as diaspore, alumina, fosterite, and periclase are used for the fabrication of high-temperature insulative firebrick without which the refining of some metals would be impossible.
