Axil said "At 2700C the nature of the electrical resistance of the structure of the reactor core could be completely reversed"
by which he means that the metal container could have a higher resistance than the initially less conductive core.
Although Axil's graph indicates alumina increasing its conductivity ( decreasing its resistivity -the inverse of conductivity)
by a factor of 100000000000 as temperature is increased to 2700 C
the alumina still has a much higher resistivity than metals at this temperature
by a factor of over 10000000.
Maintenance of high voltages inside a less conductive alumina -like ore would be unlikely, if the core contacted a more conductive metal container
