A Note on Combat® Boron Nitride Ceramic Properties by Orientation
Hot pressed boron nitride, sometimes referred to as "white graphite" has a platey, hexagonal structure. Atoms in the basal or platelet plane are held together by strongly directed covalent bonds in a hexagonal array. This type of bond, similar to that found in diamonds, yields excellent physical, thermal and electrical performance under a wide range of uses.
In contrast, the bonds between platelet layers are weak Van der Waals forces, resulting in highly directional or anisotrophic properties. Although these weak bonds can reduce the physical strength of the overall material, they impart many unique electrical and mechanical properties, most notably, its lubricious nature. Hexagonal Boron Nitride can be easily machined into complex shapes using conventional high speed cutting tools.
