Lubrication efficiency could be the Main benefit of hBN. Due to its layered crystal structure, the layers can slide freely below external force, forming a stable lubricating film around the surface area in the friction pair, which drastically minimizes friction coefficient and put on. Below distinct Doing work problems, hBN’s lubrication effectiveness demonstrates clear rewards:
Below seawater lubrication situations, the friction coefficient from the Si₃N₄-ten vol% hBN friction pair is often as low as 0.03, and also the wear level is as little as 10⁻⁶ mm/nm. This is often due to thorough impact of hydrodynamic lubrication and boundary lubrication of the floor film shaped by tribochemical reaction. Less than entire immersion water lubrication, the friction coefficient with the Si₃N₄-hBN/Si₃N₄ friction pair could be as little as 0.01, that's far reduced than that of pure Si₃N₄ (0.35 underneath the identical conditions).
In contrast, Si₃N₄ has no noticeable lubrication functionality.

For instance, inside the manufacture of solitary crystal silicon wafers, hBN-coated graphite crucibles can stand up to large temperatures previously mentioned 1600°C, and also have excellent lubrication and anti-adhesion Homes, which could drastically Enhance the yield and high quality of silicon wafers. Additionally, hBN has superb electrical insulation overall performance, and its dielectric continuous is reduced, which is well suited for superior-temperature insulation parts in electronic devices.
Si₃N₄’s superior-temperature resistance is likewise exceptional, using a decomposition temperature above 1900°C. It may possibly retain steady mechanical properties from the temperature variety of 1200°C, but its oxidation resistance is somewhat inferior to hBN. When Employed in an oxidizing environment above 1300°C, a dense SiO₂ oxide movie will probably be fashioned within the area of Si₃N₄, which could stop even further oxidation of the material, though the oxide film will peel off at better temperatures, affecting its assistance lifestyle.
Concerning chemical balance, both equally components are immune to most acids, alkalis, and organic solvents.
