Mechanochemical synthesis and spark plasma sintering of. Dec 15, 2014 The cerium silicides, Ce 5 Si 3, Ce 3 Si 2, CeSi, CeSi 2− y, and CeSi 2− x, have been prepared from the elements by mechanochemical processing in a planetary ball mill.Preparation of the cerium silicide Ce 5 Si 4 was unsuccessfully attempted and potential reasons for this are discussed.
