Zirconium is regarded as both a reactive and refractory metal because of its high melting point of 1852 °C. However, zirconium is not suitable for high temperature applications because of its reactivity. Zirconium reacts with many metallic and nonmetallic elements at elevated temperatures, that is why zirconium needs a clean surface and argon shielding in welding.

1.2 Zircon structure. Zircon is a mineral that is an orthosilicate accessory. Its chemical formula is ZrSiO 4 (Z = 4) with the space group I 4 1 / amd.The zircon structure is made up of chains of consecutive, edge-shared SiO 4 and ZrO 8 polyhedra that pass along the c axis. The structure is rather wide; it incorporates "channels" of evidently vacant sixfold sites that run in …
