摘要：
Interactions in the V2O5 -AlN system have been studied using chemical analysis, X-ray diffraction, and thermal analysis in combination with mass spectrometry. The results demonstrate that heating mixtures with AlN/V2O5 molar ratios >= 2.33 to above 1100 degrees C leads to the formation of the vanadium nitrides V2N, VN0.81, and VN among condensed reaction products. No formation of solid solutions of aluminum in vanadium or vanadium aluminides during heating has been detected in the temperature range studied. Chemical interaction of V2O5 with AlN meets Baikov's transformation sequence principle: V2O5 -> VO2 -> V4O7 -> V3O5 -> V2O3 -> VO -> V.
