Production of carbon-based composite materials as components of aluminium production cells

摘要: A method of producing a component an aluminium production cell made carbon-based composite material containing refractory hard metal boride, carbide, oxide, nitride or combinations mixtures thereof and aluminium, titanium, silicon zirconium, alloys compounds thereof, comprises firstly providing reaction mixture zirconium precursors which react to form the compound, optional fillers additives. The is mixed with particulate carbon in amount from 1 20 parts by weight for part mixture; colloidal binder at least one silica, alumina, yttria, ceria, thoria, zirconia, magnesia, lithia, fully wet particles. resulting compacted dried heated initiate self-propagating micropyretic reaction.
