4N vanadium refers to high-purity vanadium materials.
Vanadium is a chemical element located in the fourth period, group 5 (vanadium subgroup) of the periodic table, with the element symbol V, atomic number 23, and relative atomic mass 50.9415. Vanadium is a shiny silver gray metal with hard and ductile properties, a relative density of 6.11g/cm ³ (19 ℃), a melting point of 1917 ℃, and a boiling point of 3421 ℃. The resistivity of vanadium is 24.8x10 ⁻⁸Ω· m (20 ℃). The important compounds of vanadium include vanadium dioxide, vanadium pentoxide, vanadate salts, and various oxidation states of vanadium halides. In nature, vanadium mainly exists in minerals such as green sulfur vanadium ore and vanadium lead ore. Vanadium is mainly used in the preparation of alloy steel and catalysts.
High purity vanadium materials, such as 4N vanadium, refer to vanadium materials with a certain level of purity. In chemistry, "N" represents "Nines", which refers to materials with a purity of 99.99% or higher. Therefore, 4N vanadium refers to vanadium materials with a purity of 99.99% or higher, and belongs to high-purity vanadium products. This type of high-purity vanadium material has important applications in many high-tech fields, such as aerospace, electronics industry, chemical industry, and so on.
