Abstract
A method for removing residual oxygen from a growth solution prior to liq phase epitaxial crystal growth comprising the steps of disposing the materials in a containment vessel of a solid oxide electrolyte material under a protective atmosphere, heating the materials to form a liquid charge in the containment vessel, placing an electrode of an inert conducting solid in physical contact with the liquid charge, and applying a DC electric potential between the electrode and the containment vessel, the electrical contact to the containment vessel being made through a porous metallic coating of an inert metal on the outside surface of the containment vessel in the region where the liquid charge is contiguous to the inside surface of the containment vessel, the porous coating being relatively positive and the electrode being relatively negative.
