/skut"euh rud'uyt/, n.a mineral, chiefly cobalt and nickel arsenide, (Co,Ni)As3, with some iron, occurring in the form of gray cubic crystals, usually in masses: a source of cobalt and nickel.[1865-70; < G Skutterudit, named after Skutterud in Norway; see -ITE1]
* * *▪ mineralone of a series of cobalt and nickel arsenide minerals that occur with other cobalt and nickel minerals in moderate-temperature veins. The members of the series, which all form crystals of isometric symmetry, are skutterudite and smaltite; their compositions approach that of (Co,Fe,Ni)As2−3.
