In this study, the wet chemical method was used to synthesize -doped hydroxyapatite samples, and the effects of varying the amount of addition on structural, thermal, and biocompatibility in vitro properties were studied. In addition, the synthesized compounds were modeled in order to conduct theoretical research. and data confirmed the formation of biphasic compositions for all samples. More than of samples showed the formation of phase, whereas the minor phase was Addition of resulted in an increase in phase from to The lattice parameters unit cell volume lattice strain ), and lattice stress varied when was added as a dopant. The crystallite size and crystallization percentage decreased as the content increased, however, the anisotropic energy density gradually increased. Thermal analysis results confirmed that all samples seemed to be thermally stable. The addition of did not result in any notable morphological modifications. Cell viability values of the -based sharply decreased as a result of an increase in the additive. Theoretical studies show that when the amount of in the -based structure increases, the bandgap energy decreases from to . An increasing density and decreasing unit cell volume have been observed, as confirmed by the theoretical results. In addition, there was a decrease in crystallinity as well as an increase in anisotropic energy density.
