Boron nitride as solid lubricant [SubsTech]

2012-6-2 · The main advantage of boron nitride as compared to graphite and molybdenum disulfide is its thermal stability. Hexagonal boron nitride retains its lubrication properties up to 5000°F (2760°C) in inert or reducing environment and up to 1600°F (870°C) in oxidizing atmosphere. Boron nitride has high thermal conductivity.
