Vanadium

The biological image of the transition element vanadium ferments a great deal of contradiction - from toxicity to essentiality. Importance of this element as micro-nutrient is yet to be unequivocally accepted by biologists and biomedical scientists. In spite of toxicity, it seems interesting to analyze the different biological roles of the element.

Vanadium Market Report

Vanadium is a soft, silver-gray metallic element which can be either derived from mined vanadiferous titanomagnetite (VTM) or produced as by-product of vanadium-bearing pig iron slag and petroleum residues and spent catalysts. Around 92% of vanadium produced in the world is alloyed with iron to produce ferrovanadium, an additive to improve steels.
