López-Vergara, Fernanda; Galdámez, Antonio; Manríquez, Víctor (Sociedad Chilena de Quimica, 2013)The solid solutions Cu2Fe1-XCoXSnS 4, with stannite-type structure are stable up to about 800C. The electrical properties of the Cu2Fe1-XCo XSnS4 ceramic were investigated by complex impedance. The real and imaginary ...

Manríquez, Víctor; Galdámez, Antonio; Villanueva, Aníbal; Aranda, Pilar; Galván, Juan Carlos; Ruiz Hitzky, Eduardo (Elsevier Science Ltd, 1999)In0.20Mn0.70PS3, Ga0.28Cd0.58PS3 and In0.33Cd0.50PS3 compounds were synthesized by insertion of trivalent cations (In3+ and Ga3+) into MPS3 (M = Mn, Cd). The insertion process requires the previous intercalation of K+ ions ...
