Zsbn is unique because it is a composite material that combines the best properties of hot-pressed boron nitride with the non-reactivity and strength/wear resistance of zirconia. 188.8.131.52 boron nitride and carbide. boron nitride is a competitor to pyrocarbon as an interphase material, as it has a similar mechanical behavior but a much better resistance to oxidation, because it forms a liquid oxide instead of evolving gas. accordingly, its insertion in cmcs has been chiefly made as a first fiber coating. Hexagonal bn (h-bn) ceramic is usually used to make bn crucible. cubic boron nitride (c-bn) is used as an abrasive and is an ideal material for heat spreaders. amorphous boron nitride (a-bn) layers of amorphous boron nitride (a-bn) are used in some semiconductor devices.
