Samples of hydroxyapatite modified with strontium ions were synthesized. The amount of doped ions during the synthesis varied from 0.1 to 0.5 mol. The phases were identified and their crystallographic parameters were determined using X‑ray phase and X‑ray structural analysis. It was found that there is an isomorphic substitution of calcium ions by strontium ions in the samples of strontium‑modified hydroxyapatite. The surface of the samples was studied using scanning electron microscopy and X‑ray spectral microanalysis and an assessment was made of the quantitative distribution of chemical elements on the surface: strontium is uniformly distributed over the surface of the synthesized samples. An assessment of the antibacterial properties in relation to Escherichia coli and Staphylococcus aureus bacteria was carried out. All samples have bactericidal properties
