Title: Synthesis of the p-type semiconducting ternary oxide CuAlO{sub 2} using the Pechini method

Abstract

Graphical abstract: - Highlights: • We have prepared single-phase samples of the semiconducting oxide CuAlO{sub 2} using the Pechini method. • Reaction times are reduced relative to conventional solid-state synthesis. • Products have high surface area suitable for ceramic processing. • Product composition is dictated by thermodynamic control; CuAl{sub 2}O{sub 4} is obtained preferentially at lower temperature. - Abstract: The synthesis of the delafossite phase CuAlO{sub 2} using the Pechini method was investigated. Powder X-ray diffraction data showed that pure, single-phase samples were obtained after only 3 h heating at 1100 °C. CuAl{sub 2}O{sub 4}, which contains Cu(II) rather than Cu(I), was the dominant phase between 700 and 1100 °C. Conversion to CuAlO{sub 2} is promoted by the positive entropy change associated with the evolution of oxygen. No mixed Cu–Al oxide was formed below 700 °C.
