  • Refractory Ceramics - an overview | ScienceDirect Topics

    2010-6-16 · Joule melters employ large refractory ceramic baths (several square meters in area and 1 m or so deep) containing ceramic electrodes to directly heat mixtures of glass frit and nuclear waste to a molten state. The melt is then poured into steel transport canisters in which it cools slowly to yield a borosilicate glass.
