Vanadium Oxides: Synthesis, Properties, and Applications
网页2019年1月18日 · Vanadium oxide, below T c, can exist in two phases: stable phase/M 1 phase (β = 122.62°) and metastable phase/M 2 phase (β = 91.88°). The metastable phase is normally induced by either doping or stress.
Vanadium oxide | chemical compound | Britannica
网页In oxide: Metal oxides. For example, vanadium oxide (VO 2) is an amphoteric oxide, dissolving in acid to give the blue vanadyl ion, [VO] 2+, and in base to yield the yellow-brown hypovanadate ion, [V 4 O 9] 2−. Amphoterism among the main group oxides is primarily found with the metalloidal elements or their close neighbours. Read More ...
