Crystalline structure and electrical properties of Dy1-XCaXMnO3 solid solution
Boletín de la Sociedad Española de Cerámica y Vidrio, 2002 Solid solutions corresponding to the Dy1-xCaXMnO3 system, x=0.0 to 0.60 have been studied. The powders were prepared by solid state reaction of the corresponding oxides and carbonates. Sintered bodies were obtained by firing between 1250 and 1450ºC.
