抄録

Powders of CuMO<SUB>2</SUB> (M=Fe, Al, Y, Ga) with delafossite structure were synthesized by a gel technology using citric acid (CA) as a complexant. Heating of a mixed solution of CA, H<SUB>2</SUB>O and the constituent metals at 130°C gave a brown transparent gel. The gel was preheated at 350°C to give a powder precursor which was subsequently converted to oxides by heat-treating it at 700°C-1050°C for 12h either in N<SUB>2</SUB> or in air. X-Ray diffraction and Raman scattering analyses showed that all the samples are virtually of single-phase without any indication of secondary phases. Pure CuMO<SUB>2</SUB> was successfully synthesized by the CA-based gel technology at lower temperature and with shorter sintering time when compared with those for the conventional solid-state reaction technique.
