Meteoritic Zircon

Science, 1964
Zircon (ZrSiO 5 ) has been identified as an accessory mineral in the Vaca Muerta mesosiderite and in the troilite nodules of the Toluca iron meteorite. The occurrence in Vaca Muerta is a new discovery confirmed by electron-probe microanalysis of a grain in a polished section of the meteorite.

Zircon-quartzite and zircon-clay refractories

Refractories, 1980
The authors have investigated the properties of zircon-quartzite and zircon-clay refractories. They have established that the use of both quartzite and zircon in the masses permits the preparation of refractories which expand during heating and have a fairly high refractoriness and softening point under a load of 0.2 MPa; in this connection ...

Production of coloured zircon pigments from zircon

Journal of the European Ceramic Society, 2007
Zircon (ZrSiO 4 ) pigments are commonly used in the ceramic industry for glazes due to their high chemical stability and superior resistance to the dissolution during firing in glazes. These pigments are made by calcining a mixture of SiO2, ZrO2, a dopant ion which produces the colour and mineralizer.

Li diffusion in zircon

Contributions to Mineralogy and Petrology, 2007
Diffusion of Li under anhydrous conditions at 1 atm and under fluid-present elevated pressure (1.0–1.2 GPa) conditions has been measured in natural zircon. The source of diffusant for 1-atm experiments was ground natural spodumene, which was sealed under vacuum in silica glass capsules with polished slabs of zircon.

Zircon Synthesis and the Properties of Zircon-Based Luminophores

Glass and Ceramics, 2016
The conditions for the synthesis of zircon crystals from a fluxed solution are studied. It is proposed that CaCl2 be used as flux. Samples of luminescent zircon are obtained with activation by Dy3+ and Eu3+ ions. The luminescence properties of the materials obtained are investigated and the luminescence spectra of pure zircon (synthesized using Li2MoO4

Sintering of Lanthanum Zirconate

Journal of the American Ceramic Society, 1999
Lanthanum zirconate (La 2 Zr 2 O 7 ) was prepared by coprecipitating lanthanum nitrate and zirconyl oxychloride at pH 10, followed by ethanol washing. The initial high surface area of ∼304 m 2

Structure and Chemistry of Zircon and Zircon-Group Minerals

Reviews in Mineralogy and Geochemistry, 2003
Zircon (ZrSiO4) is a common accessory mineral in nature, occurring in a wide variety of sedimentary, igneous, and metamorphic rocks. Known to incorporate an assortment of minor and trace elements, zircon has the ability to retain substantial chemical and isotopic information, leading to its use in a wide range of geochemical investigations, including ...
