摘要: A new cubic perovskite-like vanadium bronze of composition Na0.25Cu0.75VO3 , with a lattice parameter 7.2517(1) A, is obtained by reacting NaVO3 V2O5 and Cu2O at 1100°C 8 GPa. It exhibits metallic conduction, sharp change in resistivity above 200°C, and, presumably, undergoes phase transition near 280°C. The thermal properties the are studied air helium normal pressure.
