Abstract
For a non-reactive metal/oxide system, when the partial pressure of oxygen in the furnace, P-O2, is increased progressively, the contact angle theta h ardly varies up to a threshold value P-O2(t) at which a decrease of theta i s initiated. The experimental data on the O-2-wetting transition in metal/o xide systems are discussed by means of a statistical thermodynamic model of adsorption at metal/vapour and metal/oxide interfaces developed previously for binary solutions. An equation is established allowing the P-O2(t) valu e of a metal/oxide couple to be calculated from known values of thermodynam ic properties of mixing of liquid metal-oxygen bulk solutions.
