The spherical materials TiO-SiO-PO/CaO, TiO-SiO-PO/LaO, and TiO-SiO-PO/ZnO deposited on the Tokem-250 cation exchanger have been synthesized with an alcoholic solution by the sol-gel method. The macroporous cation exchanger Tokem-250, which has high Ca, Zn, and La ion selectivity, was used in the present study. This material has the ability to precipitate and mineralize calcium phosphates on its surface in biological media, since it has high porosity, a homogeneous structure with a uniform variation of elements, and the presence of active centers (Si, Ti) on the surface.

The TiO-SiO-Ag/fiberglass with antibacterial properties under UV light irradiation was synthesized. The effects of compositions of TiO-SiO-Ag/fiberglass, optical, and textural characteristics on the antibacterial activity were studied. The TiO-SiO-Ag film was coated on the surface of fiberglass carrier filaments.

A facile synthesis method was developed to synthesize TiO-SiO-PO/CaO or TiO-SiO-PO/ZnO with a core-shell structure. The carboxylic cation exchanger Tokem-250 has a high selectivity for Ca/Zn ions and was used in this study. The framework of the material in the shell was TiO-SiO-PO, and the inner part was filled with CaO (sample TiO-SiO/CaO) or ZnO (sample TiO-SiO-PO/ZnO).

Spherical biomaterials based on Tokem-200 cationic exchange resin were synthesized from solutions by the sol-gel method. The material framework is represented by TiO-SiO, and the inner part is filled with CaO (sample TiO-SiO/CaO). A stepwise heat treatment (drying at 60 °C) annealing at 150, 250, and 350 °C, each for 30 min, at 600 °C for 6 h, and 800 °C for 1 h is required to obtain a homogeneous material.

The calcium phosphate spherical material with a hierarchical structure has been used as a bone implantation material. To improve the properties of the implant material, the compositions of calcium phosphate, silicon, and titanium are crucial. The presence of silicon on the surface of the phosphate-calcium material accelerates the bonding of the implant with the bone (osseointegration).
