Abstract
The results of the studies of the initial structure of wurtzitic boron nitride particles produced from graphite-like BN in shock waves with and without addition of water have been discussed. The structure of wBN particles produced with an addition of water after the deformation processing by high pressure (3 GPa) at room temperature and rolling with a shear has also been considered. It has been shown that the size in the prismatic section of wBN particles synthesized with an addition of water is always larger than that of wBN particles synthesized without additions. The high pressure-room temperature processing of the wBN powder produced with a water addition has been shown to contribute to the grinding particles mainly in the developed (basal) surface. During the rolling of such a powder the particles have been reduced both in the developed surface and through the thickness, and the substructure has been transformed due to plastic deformations (lattice, rotational, by twinning).
