Correlations of phases are studied in the system of В-В2О3 and it is set that В6О is stable, and В2О metastabil'noy the phases of this system. Were synthesized boron suboxide В6О, boron subnitride В6N and specimens of the triple system of B-BN-B2O3 . A X-ray analysis and measuring of microhardness of the synthesized materials is executed. Within the limits of models of fenomenologichnoy thermodynamics the calculation of diagram of fusibility of the triple system of B-B2O3-BN is executed at 5 GPa.
