S. Yuan et al., MODELING AND SCALEUP OF GALVANIC DEOXIDATION OF MOLTEN METALS USING SOLID-ELECTROLYTE CELLS, Journal of the American Ceramic Society, 79(3), 1996, pp. 641-650
Argon and induction stirred copper melts were deoxidized at different
temperatures by short-circuiting a solid electrolyte cell, The solid e
lectrolyte cell consisted of an yttria-stabilized zirconia tube closed
at one end, The tube interior was Bushed with a reducing gas and the
tube was immersed in the copper melt, A layer of porous Ni-ZrO2 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 a
nd ionic conductivity of the electrolyte, short-circuit resistance, an
d flow rate of the reducing gas, The deoxidation model was used to dis
cuss process optimization and scaleup.
