Structural study by energy dispersive X-ray diffraction of amorphous mixed hydroxycarbonates containing Co, Cu, Zn, Al

Abstract

A non commercial θ–θ energy dispersive X-ray diffractometer equipped with a solid state detector has been used for the determination of the amorphous structures of nine mixed hydroxycarbonates containing Co, Cu, Zn and Al. Energy dispersive X-ray diffraction (EDXD) provides information about the local order around the divalent metal ions and Al^III. An octahedral configuration around all the cations was found. Debye functions were calculated and compared with the experimental curves.
