Abstract
The present study demonstrates that the sine rule is useful for examining the interfacial free energies at solid－liquid-gas interface, when the dissolution reaction from solid ceramic to molten metal has occur and reached equilibrium. The mean value of the interfacial free energy between carbon saturated molten nickel and graphite obtained is 1.89±0.05J･m－2, and one of the surface free energy of graphite is 0.75±0.10J･m－2.
