Thermodynamic data for calcium-based alloys from a new galvanic method

A new galvanic method is used for measuring the Gibbs energies of formation of alkaline earth based alloys which were neither studied by classical electrochemical cells, nor by any other method. Direct elaboration of alloys is made by cathodic polarization of pin point electrode. Application to (Al, Ca), (Ag, Ca), (Ca,Cu), (Au, Ca) alloys is given.
