Physical properties:

Zirconium, atomic number 40, atomic weight 91.224, is a silver-gray metal with a steel-like appearance and luster. Zirconium easily forms an oxide film on its surface in the air, which is lustrous and looks similar to steel. Zirconium has corrosion resistance, but is soluble in hydrofluoric acid and aqua regia; at high temperatures, it can react with many elements to form solid solution compounds. The corrosion resistance of zirconium is better than that of titanium, and is close to tantalum and niobium. In view of the good plasticity of zirconium, it is often processed into plates, wires, etc. Zirconium can absorb a large amount of oxygen, hydrogen, nitrogen and other gases when heated, and can be used as a hydrogen storage material.


As a relatively scarce resource, zirconium is widely used in electronics, ceramics, glass, petrochemicals, building materials, medicine, textiles and daily necessities.
