otavite Min.|əʊˈtɑːvaɪt| [ad. G. otavit (O. Schneider 1906, in Centralbl. f. Mineral., Geol. und Paläont. 389), f. Otavi, name of a town in northern South West Africa: see -ite1.] Naturally occurring cadmium carbonate, CdCO3, occurring as crusts of minute rhombohedral crystals usu. white or greyish white in colour.
1906Jrnl. Chem. Soc. XC. ii. 620 A new mineral which is named otavite, after the locality. 1943Mineral. Abstr. VIII. 366 Otavite, previously described as a basic carbonate of cadmium from Tsumeb, South-West Africa, forms thin crusts of minute rhombohedra often in parallel growth on smithsonite. X-ray powder photographs agree with Zachariasen's (1928) determination for artificial CdCO3. 1967Soviet Physics: Crystallogr. XII. 417 Artificial otavite, CdCo3, crystals were obtained, which were activated by Co+2 so that EPR spectra of the magnetic Co+2 ion were observed at varying orientations of the external magnetic field at 4·2°K. |
