The body of the cermet sintered reaction; cell eletrolitica aluminium production and component of this cell, method of production of aluminium by eletrolise, process for the formation of the body.
The body of the cermet sintered reaction; cell eletrolitica aluminium production and component of this cell, method of production of aluminium by eletrolise, process for the formation of the body.
Cermet body formed by reaction entering at pressures ranging from subatmospheric to superatmospheric of admixed and shaped reactants, which can be elements, compounds, intermetallic compounds and/or alloys, in stoichiometric proportions to substantially form 30-95 mole percent of first phase or phases being boride, carbide, nitride, silicide, sulfide or combination thereof of one or more of the elements of Groups 2a, 3a exclusive of B, 4a, 2b, 3b including lanthanide and actinide series elements, 4b, 5b, 6b, 7b and 8, and 5-70 mole percent of second phase or phases being metal, alloy, intermetallic compound or combination thereof of one or more of the elements of Groups 3a exive of B, 4a, 1b, 2b, 4b, 5b, 6b, 7b and 8, wherein the maximum grain size of the first phase or phases is substantially not greater than 10 mu m and which body contains 0 to 4 weight percent oxygen. This cermet body is useful in component in electrolytic cell for aluminum production.
