Tantalum metal is a hard, ductile heavy material, which chemically is very similar to niobium. Like this, tantalum metal easily forms a protective oxide layer, which makes it very corrosion-resistant. Its color is steel grey with a little touch of blue and purple. Most tantalum metal is used for small capacitors with high capacity, like those in cellphones. Because tantalum metal is nontoxic and well compatible with the body, it is used in medicine for prostheses and instruments. Tantalum metal is the rarest stable element in the universe, however, Earth has large deposits.
