Abstract: The paper presents experimental results of the synthesis under high pressure and temperature conditions of individual nano- and micron-sized heterodiamond crystals from mixtures of carbon nitride and melamine with boron. Heterodiamonds have the basic structure of cubic boron nitride, in which carbon occupies the positions of boron and nitrogen, and oxygen – only nitrogen ones. It is established that oxygen is responsible for the unit cell of boron nitride increase. It can enter to the lattice only if there is a deficit of nitrogen relative to boron.
Keywords: high pressure and temperature, boron nitride, carbon, boron, synthesis, heterodiamonds.
