D. Spinel-Bonded Spinel Refractories
Pure spinel (spinel-bonded spinel, rebonded spinel) refractories have also been
developed for specialist applications. They have much better resistance to alkalis
than other spinel-containing refractories, so they can be potentially used in, e.g.,
glass industry furnaces (regenerator and melting furnaces), induction furnaces,
and high soda waste-melting incinerators. Windle and Bentley (64) determined
that rebonded spinel bricks exhibit exceptional tolerance to alkali in combination
