Abstract
Component of electrowinning or electrorefining cell, which component in use is normally covered 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 form 10-90 mole percent of first phase or phases being boride phase or phases of one or more of the elements of Groups 4b, 5b and 6b, and 10-90 mole percent of oxide phase or phases being predominantly Al.sub.2 O.sub.3 ; and which phases have a maximum grain size substantially not greater than 15 .mu.m. Also production cell, and method of producing aluminum in such cell, with the reaction sintered ceramic component.
