Abstract
THE crystal structures of the different phases of the iron-silicon system have been worked out by Phragmen1 with the exception of one, which he described as Fe3Si2 (25.0 per cent Si). This phase usually appears together with a (solid solution of silicon in ferrite) or E (FeSi). The composition seems to correspond to 23–25 per cent Si, but it is difficult to obtain it in a pure form. Furthermore, Greiner and Jette2 showed that the n phase was stable only between 825 and 1030° C.
