Skutterudite is a cobalt arsenide mineral containing variable amounts of nickel and iron substituting for cobalt with the ideal formula CoAs 3. Some references give the arsenic a variable formula subscript of 2–3. High nickel varieties are referred to as …

The term skutterudite originally refers to a naturally occurring mineral with the chemical formula CoAs 3, which was mined as a source of cobalt and nickel in Skutterud, Norway.

2017年4月1日 · Skutterudites derive from the aristotype CoSb 3, a diamagnetic (Co 3+, 3 d 6) narrow band gap (∼0.2 eV) semiconductor with high carrier mobility and relatively large effective electron mass reaching a ZT < 0.8.

2024年11月1日 · In this article, we comprehensively reviewed the thermoelectric proper-ties of skutterudites-based materials. We discussed the various synthesis methods like non-chemical and chemical methods for the synthesis of the skutterudites materials …

2016年10月13日 · A cutting-edge development in spacecraft power systems is a powerful material with an unfamiliar name: skutterudite. No extension cord is long enough to reach another planet, and there's no spacecraft charging station along the way.

skutterudite, one 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)As 2−3.

2019年12月18日 · Since the discovery of skutterudite (an arsenide mineral (Co, Fe, Ni)As3) in 1845 in Norway, valuable research on isotypic Sb-based skutterudites achieved high-quality thermoelectric (TE) p- and n-type leg materials with remarkably high figure-of-merit ZT, forming...

2017年1月7日 · Skutterudite is a material consisting of cobalt and arsenic, often contaminated by rare earths. It belongs to the class of sulfides. It owes its name to the city of Skutterud in Norway, which is where this naturally occurring mineral, CoAs 3, was first discovered in 1928.

Several research groups, mostly in the U.S., are now working on understanding and optimizing the transport properties of skutterudites. Most of the efforts are focusing on reducing the lattice thermal conductivity by filling the empty octant cages …

1994年8月10日 · By replacing the transition metal or the pnicogen atom by two of its neighboring elements and ensuring that the number of valence electrons is retained, many ternary phases can be successfully derived from the original CoAs 3 skutterudite structure.
