Properties of rare metal zirconium include physical properties and chemical properties of zirconium.

Zirconium is one chemical element. The chemical symbol of zirconium is Zr and atomic number of zirconium is 40. Zirconium is a silvery white transition metal. The surface of zirconium is easy to form a layer of oxidation film and has luster. So the appearance of rare metal zirconium is similar to that of steel.

Zirconium is featured by corrosion resistance. Zirconium is insoluble in hydrofluoric acid and aqua regia; At high temperatures, zirconium reacts with non-metallic elements and many metallic elements to form solid solution compounds. Zirconium has good deformability, so it is easy to process zirconium into zirconium plate, zirconium wire etc.. Zirconium is able to absorb a large number of oxygenon hydrogen, nitrogen and other gases when zirconium is heated. So zirconium can be used as hydrogen storage material. The corrosion resistance of zirconium is good and is close to that of niobium.

Zirconium and hafnium have similar chemical properties and history. Zirconium and hafnium accrete and they all contain radioactive substances. In the earth's crust, the content of zirconium ranks twentieth and is almost equal to that of chromium. Zirconium minerals having industrial value in nature are mainly zirconite and baddeleyite.
