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 ...

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

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.
