zirconolite Min.|zɜːˈkɒnəlaɪt| [ad. Russ. tsirkonolít (L. S. Borodin et al. 1956, in Dokladȳ Akad. Nauk SSSR CX. 845): see zircon and -lite.] A mixed oxide of (essentially) calcium, zirconium, and titanium, now regarded as identical with zirkelite.
1957Chem. Abstr. LI. 6440 (heading) The new mineral zirconolite, a complex oxide of the type AB3O7. 1975Amer. Mineralogist LX. 341/1 Zirconolite, CaZrTi2O7, was described in 1956..as a new mineral and the zirkelite of Blake and Smith was considered to be zirconolite... New analyses and X-ray studies of type material show that all these are a single mineral species of composition (Ca,Th,RE)Zr(Ti,Nb,Fe)2O7. The name zirkelite has priority. 1980Nature 17 Jan. 282/1 Synthetic zirconolite, CaZrTi2O7, has attracted interest recently, as it has been proposed as a constituent phase of an artificial rock (SYNROC) which may immobilise, in solid solution, the elements occurring in high-level nuclear reactor wastes. 1981[see zirkelite]. |
