Image of cubic zirconia, a crystalline form of zirconium dioxide
Facts about Zirconium:
- Zirconium: Zirconium is a lustrous, greyish-white metal that is solid at room temperature.
- Fun fact about Zirconium: Zirconium is typically found in S-type stars which feature bands of zirconium oxide. The primary commercial source of Zirconium is the mineral Zircon, which is also the source of the element’s name.
- Chemical symbol: Zr
- Atomic number: 40

Zirconium was identified in 1789 in the mineral zircon by Martin Heinrich Klaproth. While the name zircon is derived from the Arabic zargun, meaning gold-hued, zircon occurs in many colours. Zirconium has good strength at elevated temperatures and is resistant to corrosion by many acids, which lends to its use in nuclear reactor cores and where corrosive agents are involved. Oxides of Zirconium have high refraction index and rank high on the hardness scale and are therefore good gem materials. The oxides are also used for laboratory crucibles, furnaces and can be formed into ceramic knives. Zirconium compounds are used for medical applications in some dental implants and crowns, knee and hip replacements, and other prosthetic devices.
