Abstract
Introduction of iron ions into hydroxyapatites imparts some useful properties to ceramic materials. We created a porous ceramic material from nanosized iron-substituted HA and studied its physico-chemical and biological properties. It is shown that all the iron ions introduced in the course of synthesis enter into the composition of HA and are characterized by the oxidation state +3. The size of crystals after thermal treatment at 9000 C does not exceed 100 nm, the crystals’ shape is close to a sphere. Porous materials from nanosized iron-substituted hydroxyapatites support adhesion and growth of anchorage-dependent cells of mammals.
