“…In this phase diagram, WSi2 and W5Si3 are shown as ordered alloys. Other crystal structures for the tungsten silicides were also reported (Dauben et a1 1956, Matjusenko et a1 1959, Matjusenko 1964, d'Heurle et a1 1980. The reported crystal structures for the tungsten silicides are summarised in table 1.…”

“…This paper gives a short review of results of the non-relativistic and relativistic band calculations on tungsten in the BCC structure. The non-relativistic surface consists of four different sheets (Lomer 1962,1964, Loucks 1965, Mattheiss 1965. Their main parts are described as an electron 'jack' centred at I' and hole 'octahedra' at the symmetry point H. The others are smaller pieces; electron 'lenses' along A , and hole ellipsoids at N. The relativistic APW band calculation was originally carried out by Loucks (1966).…”

The Fermi surfaces of the tungsten silicide alloys WSi2 and W3Si determined from semi-relativistic self-consistent band calculation are presented. The former consists of simple closed sheets, while the latter is constructed from two closed sheets, two multiply connected surfaces and, possibly, one electron pocket. The Fermi levels of these silicides are located in the dip of the density of states. Additionally, the relationship between the content of tungsten atoms in the alloys and its electronic properties is discussed.
