spodiosite Min.|ˈspɒd-, ˈspəʊdɪəsaɪt|
[ad. Sw. spodiosit (H. V. Tiberg 1872, in Geol. Förening. Stockholm Förhandl. I. 84), f. Gr. σπόδιος ash-grey: see -ite1.]
A phosphate and fluoride of calcium, Ca2PO4F, found as orthorhombic crystals; also, any of a series of artificial minerals having similar crystal structures but containing other elements.
1887Jrnl. Chem. Soc. LII. i. 346 In consequence of the chemical and crystallographical resemblance between spodiosite and kjerulfine, the author suggests that the two minerals may be isomorphous compounds. 1911Jrnl. Physical Chem. XV. 469 The spodiosite found at Nordmark in Sweden occurs in orthorhombic crystals. 1953Mineral. Mag. XXX. 167 These orthorhombic cell dimensions provide some justification for the inclusion by Dana of spodiosite in the wagnerite group. 1970Inorg. Chem. IX. 2264/2 Spodiosites with the general formula Ca2XO4Cl, with X = P, V, Cr, and As have been prepared. 1974Jrnl. Amer. Ceramic Soc. LVII. 102/1 Spodiosite analogs, a class of compounds related to apatites, are used in phosphors and have possible future industrial applications as laser hosts and bioceramic materials. |
