Vanadium hydride 

Molecular formula: VH2 

Molecular weight: 55.9812 

Appearance: Grey

Property: Vanadium hydride is a transition metal hydride, in which scandium, vanadium, chromium, nickel, palladium, lanthanide, actinide and other elements can form binary compounds with hydrogen. Vanadium metal absorbs hydrogen and expands its lattice. The density of hydrides is about 6% to 10% lower than that of vanadium metal. Vanadium metal becomes brittle after absorbing hydrogen. Heating to 600 ℃~700 ℃ in vacuum causes the decomposition of vanadium hydride. With the release of hydrogen, the hardness of vanadium decreases and its plasticity is restored. Vanadium hydride does not react with water or boiling hydrochloric acid, but is oxidized by nitric acid. 

Purpose: 

Hydrogen storage material: Vanadium hydride can be used as a hydrogen storage material with high hydrogen storage capacity, suitable for scientific research and industrial applications in universities. 

Chemical raw materials: Vanadium hydride can be used as a chemical raw material, especially as a catalyst or reactant in certain specific chemical reactions. 

Research application: Due to its unique physical and chemical properties, vanadium hydride has a wide range of applications in the field of scientific research, especially in materials science and energy research.
