ABSTRACT:
Compacted, granular, fused magnesia used as thermally-conducting electrical insulation in tubular, electrical resistance elements is substantially improved in thermal conductivity through the addition of 0.1 to 10.0 percent of a glass comprising CaO, B.sub.2 O.sub.3 and optionally Al.sub.2 O.sub.3.
