A stable icosahedral phase was found in a series of Cd65Mg20RE15 (RE = Y, Nd, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) alloys. These icosahedral alloys have quasilattice parameters from 0.5571 to 0.5799 nm. Electron diffraction study showed that the icosahedral quasicrystals possess a primitive icosahedral structure. The composition of alloys is fixed so that they have an e/a value of 2.15 (e/a is a ratio of valence electron number over atom number). The alloys were prepared from pure elements by induction furnace in Al203 crucibles sealed in quartz tubes with inert atmosphere.
