Abstract: The lubricity of a wide variety of solid oxides at high temperature is analysed mainly based on the existing polarisability approach. The starting point is that the interaction between ions in an oxide depends on how strongly electrons are interacting in overlapping orbitals. This is related to the polarisability of ions. From this polarisability, the interaction between cation and anion present in an oxide was calculated for binary/mixed oxides and for six new simple oxides (values for 17 oxides collected from literature) and correlated to the coefficient of friction of these oxides below their melting temperature. Based on that correlation, the mechanism of friction of these oxides is proposed.
