Tellurium and metallic (hexagonal) selenium were shown to give solid solution in any concentration. The variation of the cell dimensions with composition departs only slightly from linearity:cshows a certain tendency to contraction (this corresponds to a smaller valency angle in the chains of atoms than is required by a linear variation):avaries much less (2 percent between Se and Te) and in a manner which depends upon the preparation of the alloy (as already observed for pure selenium by H. Krebs).The presence of sharp (hkmiddot;l) lines withlne;0 in all the alloys suggests that these must be composed not of homogeneous chains (i.e., Se chains, Te chains packed together), but of composite chains, in which the homogeneous sequences must be fairly short.
