PURE VANADIUM EXHIBITS EXCELLENT CORROSION RESISTANCE IN MARINE ENVIRONMENTS.

Vanadium is a reactive metal; a sister element to niobium and tantalum. It has many attractive properties like low fusion neutron capture cross-section, low rate of neutron embrittlement, good corrosion resistance and a relatively low density. The inelastic-scattering cross-section is quite small, but the thermal neutron cross-section is large and its usefulness in thermal reactors is, therefore, limited. Vanadium is resistant to salt water, dilute hydrochloric acid and sodium hydroxide solutions. The resistance to molten lithium is excellent.
