The authors obtained spherical biomaterials of TiO 2 – SiO 2 – P 2 O 5 /MgO composition by sol-gel method. TOKEM-200, a weakly acid porous cation exchanger based on acryl-divinylbenzene was used as organic matrices. The cation exchangers were saturated with Mg 2 + ions. Sol based on titanium butoxide, tetraethoxysilane and phosphoric acid was deposited on them. The temperature condition for producing spherical materials TiO 2 –SiO 2 – P 2 O 5 / MgO were proposed. To obtain a spherical material, the treated cation exchangers were subjected to stepwise heat treatment in the temperature range from 60 to 600 °C. To study the biologically active properties of the material, the samples were immersed in simulation body fluid (SBF).
