Abstract
1386514 Conductive refractories BROKEN HILL PTY CO Ltd 9 May 1972 [31 May 1971] 21626/72 Heading C1J An electrically conductive refractory R.E. being one or more of yttrium or a rare earth excepting Ce; A being one or more of Ca, Ba or Sr and y is 0À04-0À40, is prepared by milling together the appropriate oxides or their precursors, prefiring at 1400-1600‹ C. in a reducing atmosphere, milling the product, shaping and finally firing at less than 1700‹ C. The reducing atmosphere can be 95% N 2 +5% H 2 . Stabilized ZrO 2 or A.E. zirconate can be added before or after prefiring.
