Facts about zirconium
Here are a few interesting facts about zirconium element.
- Zirconium was given its name from the Persian word “Zargun” which means gold color.
- Zirconium was discovered by the German chemist Martin Heinrich Klaproth in the year 1789 in Berlin. (The zirconium was discovered from zirconium silicate in Berlin, and this sample was taken from Sri Lanka).
- The concentration of zirconium in the earth’s crust is around 165 ppm by weight.
- Around 7000 tons of zirconium is produced annually in the entire world.
- Australia and South Africa are the leading producers of Zirconium in the world.
- Australia produces around 58% of the total zirconium in the world.
- In early ages, zirconium was used in some decorative items as well as in jewelry.
- Zirconium is also present in the sun as well as meteorites.
Properties of zirconium
Here is a list of some physical properties and chemical properties of zirconium.
Physical properties of zirconium
- Zirconium is a solid metal and it has a silvery white appearance.
- Zirconium is ductile as well as malleable metal. Hence it can be drawn into thin wires and sheets.
- There are many isotopes of zirconium (including natural isotopes and radioactive isotopes). Out of these isotopes, the most abundant isotope is 90Zr, whose abundance is around 51%.
- The melting point and boiling point of zirconium metal is 2128 K and 4650 K respectively.
Chemical properties of zirconium
- The electronic configuration of zirconium is [Kr] 4d2 5s2 and it has incomplete d-orbitals.
- Zirconium has anti-corrosive properties and hence it is used in manufacturing of surgical instruments as well as in some bulb filaments.
- The powdered zirconium is flammable.
Uses of zirconium
Here are some uses of the zirconium element.
- Zirconium is used as an alloying metal specially in the making of steel.
- Zircaloy (that contains zirconium metal) is used in nuclear applications like cladding of nuclear fuel, etc.
- Zirconium has been used as a gemstone as it has a similar appearance as that of diamonds.
- Zirconia is an oxide that contains zirconium metal in it. This zirconia has a property to resist high temperatures, hence it is used in crucibles.
- Zirconium may help in treating cancer. The research is still going on regarding this.
