An arsenide of cobalt, ideally CoAs3, that commonly contains other elements, esp. nickel, iron, bismuth, and sulphur, and is found as grey cubic crystals with a metallic lustre.
1850J. D. Dana Syst. Mineral. (ed. 3) 474 Skutterudite... Lustre bright metallic. Color between tin-white and pale lead-grey, sometimes iridescent. 1892[see nickel-skutterudite s.v. nickel n. 3 b]. 1902H. A. Miers Mineralogy 332 It is remarkable that there is another arsenide of cobalt of quite different composition, CoAs3, known as skutterudite, which is also cubic and pyritohedral. 1947Bull. Geol. Soc. Amer. LVIII. 317 In spite of repeated attempts, varying the conditions of temperature and using different fluxes, no higher cobalt arsenide other than skutterudite CoAs3 was obtained. 1968I. Kostov Mineral. 135 Skutterudite, smaltite, and chloanthite are typical intermediate- or high-temperature hydrothermal minerals. |
