The solid-liquid interfacial energy is estimated by use of the nucleation frequency of isothermal crystallization on aging in Bi{sub 0.7}Pb{sub 0.3}SrCaCu{sub 1.8}O{sub {ital x}} glassy samples above glass transition temperature. The value of solid-liquid interfacial energy {ital Q} is about 74.7 mJ/m{sup 2}. The {ital Q} value is often expressed by use of enthalpy change {Delta}{ital H}{sub {ital f}}, Avogadro's number {ital N} and molar volume {ital V}; {ital Q} = {ital C}{Delta}{ital H}{sub {ital f}}/({ital N}{sup 1/3}{ital V}{sup 2/3}). The constant {ital C} obtained is 0.38, which is between 0.32 for covalent bonded elements and 0.45 for metals.
