Abstract

1437920 GdCoO 3 ; ErAlO 3 RHONE-PROGIL SA 19 July 1974 [20 July 1973 13 May 1974] 32134/74 Heading C1A [Also in Division C7] Gadolinium cobaltite is made by grinding stoichiometric proportions of the relevant oxides together and calcining at 1200‹ C. for 15 hours in air. Erbium aluminate is made by dissolving Er 2 O 3 and Al 2 O 3 in NHO 3 followed by evaporation and roasting at 600‹ C. for 1 hour.
