Abstract
The variation of electrical resistivity with temperature has been measured for four castable zirconias: 6.0 mole % calcia-stabilised, 8.5 mole % yttria-stabilised, and 25 and 50 mole % ceria-stabilised zirconia. The calcia-and yttria-stabilised castables need to be sintered at over 2000° K to develop their electrical conductivity fully, but that of the ceria-stabilised castables is independent of sintering temperature, and is similar to that of normally prepared ceramic. The castables are discussed with particular reference to their possible application as M H D electrode materials.
