What is the chemical formula for zircon?

ZrSiO₄Zircon / Chemical formula
The ideal chemical formula for zircon is ZrSiO4 (formula unit, Z = 4) and the space group is I41/amd. Zircon is an orthosilicate and its structure consists of isolated SiO4 tetrahedra and ZrO8 dodecahedra (Figure 1).

What is zircon used for?

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.

What group is zircon?
