Abstract

"The liquid-vapor and solid-vapor interfacial energies of the system Ga-Al2O3 were determined by the sessile drop technique. The interfacial energies were found to decrease with increasing temperature and P02.

A maximum liquid-vapor interfacial energy of 581 ergs/cm² was found for a clean sessile drop at 1227°C. Values for Γ0, the excess concentration of oxygen, were calculated for both the liquid-vapor and solid-liquid interfaces. The work of adhesion between molten Ga and Al2O3 was found to increase with decreasing P02 with a maximum of 576 ergs/cm2 occurring at 927°C for a P02 of 10-22.5"--Abstract, leaf ii.
