Processing of Zirconia
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 …
