Abstract In this study, hydroxyapatites reinforced with Boron, Copper and Zinc at different rates were produced using the sol-gel method. Different amounts of metal during the production of hydroxyapatite were used to observe the amount of crystallization and morphological differences in their structures. The characterization of the metal-doped HAp was carried out by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX). The data indicated that the Ca/P stoichiometric ratios of the samples varied between 1.71 and 2, so their morphologies were different from each other. The absorption behavior of novel metal-doped HAp samples was evaluated at room temperature by UV-vis spectroscopy. In the absorption spectra of the samples, absorption bands formed in similar regions. In addition, the thermal behavior of HAp samples was investigated using TG/DTA techniques. The results of the analysis showed that heat resistance of the new synthesized samples was quite high.

Transparent glass ceramics with composition of xErF3-10PbF2-90SiO2 (mol%, x=0, 1, 2, 3, 4) were prepared by sol-gel method. The thermal behavior of the xerogels was investigated by DSC. Through non-isothermal experiments, the apparent activation energy for the crystallization of β-PbF2 phase was evaluated by the Kissinger’s method and Chen’s method. XRD and TEM were carried out to study the growth of β-PbF2 nanocrystals and the effect of Er3+ doping on it.
