In hydrothermal veins of moderate temperature and pressure.Skutterudite is a cobalt arsenide mineral containing variable amounts of nickel and iron substituting for cobalt. Materials with a skutterudite structure are studied as a low cost thermoelectric material with low thermal conductivity. Typically in medium- to high-temperature hydrothermal veins with other Ni–Cosulfide minerals. -- source link
