Boron Nitride Surface Coating of Materials with BN

Boron Nitride aerosol is a very lubricious drying spray which deposits a thin film. This powder film is very lubricious, produces an excellent anti stick surface and will also act as an oxidation. It is chemically inert to most organic and corrosive agents.

Boron nitride growth on metal foil using solid sources

Jun 14, 2013 · Largearea, atomically thin hexagonal boron nitride (hBN) thin films were grown simply by annealing in a vacuum from solid sources deposited on Ni or Co foils. Either a sputterdeposited amorphous boron nitride film or a spincoated borane ammonia film can be used as the B and N source. The hBN films were formed on the back surface of the metal foil following diffusion of B and
