Vanadium — silver gray shiny metal, No. 23 in periodic table, where it is designated as V. Atomic mass 50.9415. Valency from +2 to +5. Over 99% of Vanadium fossil — it stable 51 V. Slightly radioactive isotope 52 V has a half-life of more than 3.9 • 1017 years.
In appearance, vanadium is similar to steel. It is fairly hard, malleable and ductile metal. Its melting point is 1920 °C, boiling t° about 3400 °C, density 6.11 g/cm³. Crystal lattice is cubic volume centered, 0.3024 nm.

Chemically inert enough. Not affected by chlorinated or sea water, dilute solutions of alkalis, nitric, hydrochloric and sulfuric acid. Reacts with halogens. It forms several oxides with oxygen: VO, V2 O3, VO2, V2 O5. Dark blue VO2 — amphoteric, orange V2 O5 — acidic, other oxides are main. V2 S — sulfide, VN — nitrite and V3 Si — vanadium silicide are known. VC carbide — extremely refractory, melts at t° 2800 °C.
About ¾ of mined vanadium is used as alloying agent in preparation of heat-resistant, wear-resistant and corrosion-resistant alloys, and also as component in production of magnets. V2 O5 is catalyst, for example, in synthesis of sulfuric acid, when sulfur dioxide is oxidized to sulfur. Other oxides form persistent pigments; therefore, they are widely used in paint and varnish, textile and glass industries.
Types of rental
Production of rods from vanadium is standardized: TU 48−4-374−76. Wire Ø 0.3 — 3 mm are made of 2 grades VNP-2 and VNP-1 from vanadium ingots. Today, following rolled products are made from vanadium: sheet, bar, foil, strip, tape, pipe, wire, micron wire. Following grades of vanadium are used: VN2A-1, VV-8, VnM-0, VNM-2, VnM-1, VnP-1, VnPL-2, VnPL-1, VH-8.
