Synthesis and Characterization of Zn Doped Magnesium Hydroxyfluoride, Mg1-xZnxFOH.

A series of Zn-Doped Magnesium Hydroxyfluoride, Mg_1-xZn_xFOH) samples with Oto 0.15 of x were prepared using a sol-gel synthesis and dried with vacuum technique. XRD characterization of the samples indicated the amorphous phase of Mg_l-xZn_xFOH similarity with MgF₂. The Zn doped in magnesium hydroxyfluoride did not affected on the basic structure of magnesium hydroxyfluoride. The FUR spectra showed the samples had a broad band at 3000-3700 cm^-1 and 1620 cm^-1 was indicated of adsorbed H₂0 molecules and a bridging hydroxyl groups, respectively. The intensity of the 460, and 550 cm^-1 bands correlates to Mg-F and Mg-O vibrations. The Zn-O stretching vibration of Zn-doped magnesium hydroxyfluoride appeared at 1634 and 621 cm^-1.
