Introduction
 
Features of Vanadium powder:
 
Vanadium is a chemical element with 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.

Applications of Vanadium powder:
 
Pure vanadium is a greyish silvery metal, and is soft and ductile. It has good corrosion resistance to alkalis, sulphuric acid, hydrochloric acid, and salt waters. Industrially, most vanadium produced is used as an additive to improve steels. Its structural strength and neutron cross section properties makes it useful in nuclear applications. The metal is used for producing rust-resistant springs and steels used for making tools.
Attention in usage: The powder is innoxious and no harmful to health. While using, please avoid dust cloud formation, keep clear of acid and keep away from fire in case of exploding.
