Zircon is a zirconium silicate mineral. It is the principle source of the element zirconium (Zr) 1  usually small and inclusion-rich.  Zircon is highly resistant to weathering (maybe the most resistant of any mineral) This, and its high specific gravity, favor its concentration in placer deposits and alluvial gem gravels.
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. Mixed with vanadium or praseodymium zircon makes blue and yellow pigments for glazing pottery and tiles.ith niobium, zirconium is superconductive at low temperatures and is used to make superconducting magnets. Zirconium metal is protected by a thin oxide layer making it exceptionally resistant to corrosion by acids, alkalis and seawater. For this reason it is extensively used by the chemical industry.
