The basic properties of zirconium

Zirconium easily absorbs hydrogen, nitrogen and oxygen; the affinity of zirconium for oxygen is very strong; the oxygen dissolved in zirconium at 1000 ° C increases its volume significantly. Zirconium surface easy to form a layer of oxide film, shiny, so the appearance and steel similar. Corrosion resistance, but soluble in hydrofluoric acid and aqua regia. High temperature, with non-metallic elements and many metal elements react to form a solid solution. Zirconium plasticity, easy processing into plates, silk and so on. Zirconium can absorb a large amount of oxygen, hydrogen, nitrogen and other gases when heated, and can be used as a hydrogen storage material. Corrosion resistance of zirconium better than titanium, close to niobium, tantalum. Zirconium and hafnium are chemically similar and symbiotic two metals, and contain radioactive material.
