通过对固体电解质电池进行短路，在不同温度下对氩气和感应搅拌铜熔体进行脱氧。固体电解质电池由一端封闭的氧化钇稳定氧化锆管组成。管子内部用还原性气体冲洗，管子浸入铜熔体中。在管内壁沉积一层多孔Ni-ZrO{sub 2}陶瓷作为阳极，铜熔体为阴极。将脱氧实验建立为熔体传质、温度、电解质电子和离子电导率、短路电阻和还原气体流速的函数模型。利用脱氧模型对工艺优化和放大进行了讨论。
Argon and induction stirred copper melts were deoxidized at different temperatures by short-circuiting a solid electrolyte cell. The solid electrolyte cell consisted of an yttria-stabilized zirconia tube closed at one end. The tube interior was flushed with a reducing gas and the tube was immersed in the copper melt. A layer of porous Ni-ZrO{sub 2} cermet deposited on the inner wall of the tube served as the anode while the copper melt was the cathode. The deoxidation experiments were modeled as a function of mass transfer in the melt, temperature, electronic and ionic conductivity of the electrolyte, short-circuit resistance, and flow rate of the reducing gas. The deoxidation model was used to discuss process optimization and scaleup.
