The analysis carried out by Klaproth is dealt with again in Sect. 6.1 in Chap. 6, wherein the discovery of the metal zirconium is discussed. Today we know that zircon is a silicate, more precisely the zirconium silicate with the chemical molecular formula ZrSiO 4. Silicates and also quartz (silicon oxide) have an outstanding geological importance.

Zirconium silicate supplies ZrO2 and SiO2. An inexpensive opacifier that produces cool white colors and helps to flux high-temperature glazes. More stable than tin oxide in reduction. Only about half as effective as tin as an opacifier; generally requires 5% for some opacity, up to 15% for complete opacity. Prepared from natural zircon sands.

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 …

Optically clear cubic zirconia, known as synthetic diamond, is widely used in jewelery. Zirconium oxide exhibits three well-defined crystal structures, i.e., monoclinic, tetragonal, and cubic ( Figure 1) [ 2 ]. The monoclinic phase is stable up to 1170°C, and above this temperature it is transformed into tetragonal phase.

be excluded as deposits of zirconium are often contaminated with the radioactive ele-ments (Hopf et al. 1993). In addition, zirconium contains 2.8% of the isotope 96Zr, which has a very long half-life (Trueb 1996). The industrially most important zirconium mineral is zircon (zirconium silicate, ZrSiO 4). Because of its resistance to …
