Thermal Conductivity

8-6-2014018 - Thermal Conductivity In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized electrons. Heat can be transferred through insulators using phonons. Do

Compared to the abovementioned high-purity materials (e.g. alumina, spinel, etc.), bauxite is cheaper and, more importantly, has a lower thermal conductivity. Therefore, if lightweight bauxite with low open porosity and small pore size could be produced, it can be assumed that the costs and energy consumptions of industrial furnaces could be further reduced significantly.
