On the Ag₃Mg Supperlattice Formation

Abstract

In spite of the narrow range of α solid solution of this alloy system, the strong chemical binding between the components which was shown in a previous paper, suggests the formation of Ag₃Mg supperlattice at a lower temperature. The existence of Ag₃Mg supperlattice was confirmed from the measurement of E.M.F., electrical resistance, specific heat and X-ray diffraction. The critical temperature of this alloy is 391°, and its heat of transformation is 360 cal/mol. The structure of this alloy is not like that of Cu₃Au type, but is considered to be a layered order structure of large unit cell.
