发明名称 Electrolytic Al production with reaction sintered multiphase ceramic
摘要 Component of electrowinning or electrorefining cell, which component in use is normally in contact with molten aluminum or in electrical contact with another component which is in contact with molten aluminum. Surface and/or inner portion of component is made of ceramic body formed by reaction sintering at pressures ranging from subatmospheric to superatmospheric of reactants, which can be elements, compounds, intermetallic compounds and/or alloys, in stoichiometric proportions to substantially from 5-95 mole percent of first phase or phases being boride, carbide, silicide, and/or sulfide of one or more of the elements of Groups 4b, 5b and 6b, which phases have a maximum grain size substantially not greater than 10 mu m. and which body contains 0 to 4 weight percent oxygen. Also production cell, and method of producing aluminum in such cell, with the reaction sintered ceramic component.
