Anisotropic expansion effect of Sr doping on the crystal structure of hydroxyapatite

Abstract

Sr doping in hydroxyapatite (HA) biomaterials has attracted continuing interest due to its well-known positive effects on bone formation. Inveatigating the effects of Sr on HA crystal structure is of...

Probing the influence of strontium doping and annealing temperature on the structure and biocompatibility of hydroxyapatite nanorods

“…A few reports have proved that whenever bigger Sr 2+ replaces the smaller Ca 2+ ion, bond angles and bond lengths will change and lead to changes in the crystal symmetry of HAp. 20 HAp can be synthesized using different techniques such as solid state, sol-gel, 21 chemical precipitation, 22 hydrothermal, 23 pyrolysis, using biogenic sources, 24 and combinations of these procedures. Different morphologies, mechanical properties, levels of crystallinity, and stoichiometries can be achieved for HAp based on the method employed.…”
