The superconducting state properties of the metallic glass Ca 70 Mg 30 have been investigated in the BCS-Eliashberg-McMillan framework by extending this theory to the binary metal glasses. Pseudo ions with average properties have been considered to replace both types of ions in the system. Values of the superconducting state parameters, namely electron-phonon coupling strength (λ), Coloumb pseudopotential (µ * ), transition temperature (T c ), isotope effect exponent (α) and interaction strength (N 0 V ) have been worked out using Ashcroft's potential and the linear potential due to Sharma and Kachhava along with six different forms of dielectric screening. The form factors directly obtained from the screened pseudopotential of Veljkovic and Slavic have also been used to explicitly observe the effect of the dielectric screening on T c , α and N 0 V through µ * . The results obtained established the presence of a superconducting phase in Ca 70 Mg 30 glass.
