STRONTIUM-COPPER OXIDE COMPOUND HAVING RHOMBIC LAMINATED STRUCTURE EXPRESSED BY SR37CU63O100, ITS PRODUCTION, AND ELECTRIC CONDUCTOR COMPRISING IT

摘要

PURPOSE:To obtain the title Sr-Cu oxide compd. having superior electric conductivity, etc., and being useful as electric conductor, sensor, etc., by heating a mixture of SrCO3 and CuO in a specified molar ratio in O2 atmosphere. CONSTITUTION:SrO or a compd.(e.g. SrCO3) decomposed to SrO by heating is mixed with CuO or a compd.(e.g. CuCO3 decomposed to CuO by heating in proportion of 37mol.% SrO to 63mol.% CuO. Then, the Sr-Cu oxide compd. having a rhombic laminated structure expressed by Sr37Cu63O100 is obtd. by heating the mixture at 750-950 deg.C in O2 atmosphere.
