Abstract

The standard Gibbs energies of formation of CaC2, SrC2, and BaC2 were determined by an equilibration technique at temperatures ranging from 1223 to 1673 K, yielding the following results: Ca (l)+ 2C (s)= CaC2\GDG\dg = -90,100(\+-500)- 11.0(\+-1.1)T [J/mol]Sr (l) + 2C (s) = SrC2 (s)\GDG\dg = -104,000(\+-1000) - 8.04(\+-2.76)T [J/mol]BA (l) + 2C(s) = BaC2 (s)\GDG\dg = -115,000(\+-1000) + 3.53 (\+-1.69)T [J/mol]
