     It is mixed with other metals to make very strong and durable alloys which are used in construction materials, tools, springs and jet engines. Vanadium pentoxide (V2O5) is used as a catalyst, dye and color-fixer.

Bahan Baku

Vanadium is a chemical element with the symbol V and atomic number 23. It is a hard, silvery gray, ductile and malleable transition metal. The element is found only in chemically combined form in nature, but once isolated artificially, the formation of an oxide layer stabilizes the free metal somewhat against further oxidation.
