Boron nitride occupies a prominent place among the most important inorganic materials and serves as a basis for many advanced technologies. Its versatility is due to a wide range of properties presented by four polymorphic modifications of BN: two graphite-like (hexagonal and rhombohedral) and two close-packed (cubic and wurtzite-like). Over the past several years, there has been a steady tendency towards a rise in the production of materials based on boron nitride. Given that most of this attention is paid to high-technology products, the development of scientific foundations is vital to produce materials possessing a given combination of physicochemical properties. This, in turn, implies the necessity of reliable data on the thermodynamic properties of BN. In this paper, we present a brief review of the calorimetric studies dealing with different crystalline forms of boron nitride.
