Hexagonal boron nitride (h-BN) is a very versatile material that is used in a number of applications due to its unique combination of properties. This paper reviews typical h-BN qualities and their applications as functional particle in coatings and as sintered parts. As an example, the EKamold® coating family is presented in detail for a variety of substrate types and applications. Furthermore a general overview is given of the effect of the binder phase for hot-pressed h-BN qualities. And finally the use of h-BN as a composite with a) zirconium oxide for side dams in steel thin-strip casting and b) with titanium diboride as evaporation boats is described in more detail.
