报告摘要：
Study of chemicalinteraction and phase relations in the binary B–X systems (X = N, P) atpressures to 20 GPa and temperatures to 3000 K have been performed bysynchrotron X-ray diffraction, electrical resistivity measurements andquenching with the aim (i) to construct equilibrium and metastable phase p–Tdiagrams of the systems using models of phenomenological thermodynamics withinteraction parameters derived from the experimental data, and thus provide aroute to the synthesis of new boron-rich B–X phases; and (ii) tocomprehensively investigate the materials recovered from high pressure – hightemperature experiments by а rich variety of characterization techniques inorder to define their structure and properties, with particular attention paidto superhard and refractory phases whose advanced properties and thermalstability could be of technological importance.
