The got phases had been researched, it was ascertain that B6O was stable, and В2О was metastable the phases of this system. Hard solutions of В6(О,N) was synthesized. Within the bounds of models of phenomenological thermodynamics was calculate the diagram of fusibility of B- В2О3-BN triple system at 5 GPa. The parameters of stability of models was taken from literature, and the parameters of co-operation was found by treatment of results of experimental study of phases equilibrium.
