Abstract
A component is made of or coated with a refractory material for use at high temperature, e.g. in an aluminium production cell, an arc furnace or an apparatus for treating molten metal. The refractory material comprises particles of a refractory metal compound selected from metal borides, silicides, nitrides, carbides and phosphides, in an oxide matrix. The oxide matrix comprises a bonding mixed oxide made of a single mixed oxide or a plurality of miscible mixed oxides. The refractory material is obtainable from a heat treated slurry that comprises: a colloidal and/or polymeric oxide carrier, suspended particles of the refractory metal compound and suspended metal oxide particles. The suspended refractory metal compound particles and the suspended metal oxide particles are both reactable with the colloidal and/or polymeric oxide to form the bonding mixed oxide.
