Hexagonal BN (h-BN) is the most widely used polymorph. It is a good lubricant at both low and high temperatures (up to 900 °C, even in an oxidizing atmosphere). h-BN lubricant is particularly useful when the electrical conductivity or chemical reactivity of graphite (alternative lubricant) would be problematic. In internal combustion engines, where graphite could be oxidized and turn into carbon sludge, h-BN with its superior thermal stability can be added to engine lubricant, ho… how to cite the same website twice apaWebJan 15, 2024 · There have been many prior studies on the thermal oxidation of hBN powder, CVD films, and composite materials (i.e. hot pressed hBN), which indicate the oxidation kinetics of BN are complex and dependent on structure and the gas phase composition.
