“…Q 3 and Q 4 species [38]. Furthermore, a band in this spectral region suggests the presence of PO 4 3-groups in the glass structure [31]. In the case of both gelderived A2 and 45S5 glasses, supplementary bands at 876 cm −1 and in the range 1419-1467 cm −1 are observed.…”

“…The average pore diameter (D) was estimated from the equation 4 V tot / S BET and micropore area (S mic ) was calculated by the t-plot method. The corresponding pore size distributions were measured using the desorption data based on the Barret Joyner Halenda (BJH) method [32].…”

“…The presence of Si–O–Si valence vibrations and Si–O– deformation vibrations shows that these bonds are not destroyed at high temperatures (Kondratowicz 2007; Yashima et al 2003; Zhang et al 2013; Letaпef et al 2014). …”

A calcium–phosphate system was obtained by sol–gel method from 0.4 M solutions based on ethyl alcohol, tetraethoxysilane, phosphoric acid, calcium nitrate, and magnesium nitrate, sodium chloride. Compositions with different contents of CaO, Na 2 O, and MgO were prepared. After maturation of the solutions, heat treatments were applied at 60 °C for 30 min; and followed by 600 °C and 800 °C for 1 h. Solution with 20 wt% MgO was found suitable for film production. The physicochemical processes of the formation of materials were studied, including the main stages: removal of physically bound and chemically bound water, combustion of alcohol and the products of thermo-oxidative destruction of ethoxy groups, and crystallization processes. The phase composition and structure of the films obtained were established at 600 °C and above when crystalline forms of SiO 2 , CaSiO 3 , Ca 2 P 2 O 7 , and complex phosphates were fixed. In the system with the addition of magnesium ions, β-cristobalite SiO 2 and stenfieldt Mg 3 Ca 3 (PO 4 ) 4 were detected; however, a crystalline sample could only be obtained at 800 °C. In the system with sodium ions, chemical compounds Ca 5 (PO 4 ) 3 Cl, NaCl, and SiO 2 were determined. A uniform film coating was formed on the surface of the substrate. The introduction of sodium oxide into the SiO 2 –P 2 O 5 –CaO system increased the bioactivity of the materials obtained.
