Zirconium (Zr) is a chemical element with atomic number 40 and represented with the chemical symbol 'Zr' in the periodic table. It was discovered by Martin Klaproth in the year 1798. This is named after a mineral Zircon as it is the most important source of zirconium.

Zirconate - Wikipedia

Zirconate. A zirconate is an oxyanion containing zirconium. Examples include Na 2 ZrO 3, Ca 2 ZrO 4 which can be prepared by fusing zirconium dioxide with e.g. Na 2 O and CaO respectively.

Today this element is widely used, as zircon, as Zirconium oxide and as the metal itself. Zirconium is to be found in ceramics, foundry equipment, glass, chemicals, and metal alloys. Zircon sand is used for heat-resistant linings for furnaces, for giant ladles for molten metal, and to make foundry moulds.
