Characterization of a series Nickel Doped Magnesium Hydroxyflouride Mg_(1-x)Ni_xFOH with XRD and FTIR

摘要

A series nickel doped magnesium hydroxyfluoride, Mg_(1-x)Ni_xFOH has been prepared by fluorolytic sol-gel method. The x values in these series were from 0 to 0,15. The samples structure was obtained as amorphous phase from XRD characterization. The XRD patterns showed any peaks like the mixing between magnesium fluoride (selllaite) and magnesium hydroxide (brucite). The IR spectra from FTIR characterization of Mg_(1-x)Ni_xFOH samples indicated the peaks of OH bridging at 3630-3000 cm~(-1), Ni-OH vibration around 660-650 cm~(-1) Mg-O vibration around 550 cm~(-1), and Mg-F vibration at 460 cm~(-1).
