摘要：

MgIn2O4, a mixed oxide with spinel structure was prepared by combustion synthesis using metal nitrates and urea as fuel. Structural, optical and electrical characterization of the same was carried out. From the diffuse reflectance spectral measurement of MgIn2O4, the band gap was found to be 4.3 eV which is higher than that of indium tin oxide (ITO). The conductivity of as prepared sample and that of the Hz-annealed sample of MgIn2O4 was 1.56 x 10(-3) and 5.57 x 10(0) S cm(-1). The particle size of the above combustion derived sample was found to be 2-3 mum (C) 2001 Published by Elsevier Science B.V.
