| Abstract: | Magnetic bioceramics based on Ca5(PO4)3OH hydroxyapatite and M-type hexagonal ferrite (HF) microcrystals has been synthesized and characterized. The material consists
of a biocompatible apatite matrix containing dispersed M-type HF particles. The latter component makes the magnetic characteristics
of synthesized ceramics significantly higher as compared to those of iron-oxide-modified bioglass ceramics currently used
in medicine. These properties increase the efficiency and prospects of using the new bioceramics in medicine, in particular,
for the hyperthermal treatment of malignant tumors. Thus, a new class of materials is created, which combine the necessary
biocompatibility and biological activity of Ca5(PO4)3OH hydroxyapatite and high magnetic characteristics of M-type HF microcrystals. |
