El circonio es un metal de transición brillante y resistente a la corrosión. Se usa mucho en reactores nucleares y como gema (circonita cúbica).

Acerca de Circonio

Lustrous and highly resistant to corrosion, zirconium is a transition metal of atomic number 40 and atomic mass 91.224. A solid under standard conditions, it has the configuration [Kr] 4d2 5s2 and an electronegativity of 1.33, and it occupies group 4, period 5, directly below titanium, whose corrosion resistance it shares. Zirconium's durability and low absorption of neutrons make it valuable in nuclear reactors, where materials must endure both heat and radiation, while its oxide, cubic zirconia, is widely used as a diamond-like gemstone. The metal belongs to the second row of the transition series.
