Hexagonal boron nitride-copper composites were prepared by hot pressing. The boron nitride in the composites possessed well-developed crystal structure charaterized with an extremely low distance between boron nitride layers. Independently on the particle size of the starting copper powder, the grains of the metal in the composites showed a narrow distribution in their size, given by the interfacial tension between the ceramic and metal phases. By the transmission electron microscopy, joints between boron nitride grains and copper granules having the highest occurrence on the boron nitride facets, represented by its (001）crystallographic planes, were observed. This confirms the strong directionalism of the metal-boron nitride interaction, mediated by π electronic orbitals of the latter.
