MATERIAL
OVERVIEW
Characteristics:
Gray or silvery, ductile metal; does not tarnish or
oxidize at room temperature. Reacts with oxygen and
halogens only when heated. Less corrosion-resistant
than tantalum at high temperature. Not attacked by
nitric acid up to 100 °C, but vigorously attacked by
mixture of nitric and hydrofluoric acids. Hot,
concentrated hydrochloric, sulfuric, and phosphoric
acids attack it, but hot, concentrated nitric acid
does not. Unaffected at room temperature by most acids
and by aqua regia. It is attacked by alkaline
solutions to some extent at all temperatures.
