“…However, an intense band ∼ 1096 cm −1 corresponds to the antisymmetric stretching of bridging oxygens in Si-OSi groups within the tetrahedron [43]. Two intense bands ∼ 1150-1153 cm −1 and 1170-1174 cm −1 are associated with the symmetric stretching vibrations of the two non-bridging oxygen atoms bonded to phosphorus atoms in O-P-O units and the symmetric stretching mode of O-P-O non-bridging oxygens indicating the formation of Q 2 phosphate tetrahedra [44,45]. Furthermore, the intense bands 1201-1206 cm −1 and 1223-1227 cm −1 are attributed to vibrations of the Si-O-Si framework and asymmetric stretching of PO 2 modes, respectively [46,47].…”

A composition of NASICON (Na 3 Zr 2 Si 2 PO 12 ) was synthesized by the solid-state reaction method using a new compound Na 2 HPO 4 2H 2 O. The X-ray diffraction patterns of all samples exhibit monoclinic Na 3 Zr 2 Si 2 PO 12 as a major phase with a very small amount of monoclinicZrO 2 . The maximum relative density (97 %) and maximum conductivity is obtained in the samples sintered at 1200 • C (N3) which is slightly higher than β-Al 2 O 3 . The activation energy is ∼ 0.20 eV for the N3 sample which is lower than for β-Al 2 O 3 . The dilatometeric study and Arrhenius plots confirmed a phase transition of NASICON from monoclinic to rhombohedral. The micro-structural study of the samples done by scanning electron microscopy (SEM) indicated a significant influence of the processing conditions on the microstructures. Raman spectroscopy demonstrated that the sample N3 exhibits minor structural changes compared to other samples.

“…7) In addition, these glasses have attracted a considerable attention because of their wide applications in the field of glass ceramics, thermal and mechanical sensors, reflecting windows as well as their potential use as layers for optical and optoelectronic devices, etc.. 8) Studies of Na2O-CuO-Bi2O3-P2O5 quaternary glasses 9), 10) reported that the addition of CuO or Bi2O3 increase the glass transition temperature and depolymerize phosphate chains. 9) According to Chahine et al,10) the Bi2O3 in these glasses behaves as a network former and is incorporated in the network as BiO6 units. This study examined the effects of the Bi2O3 content on the physical and optical properties as well as the structure of ZnOBi2O3-P2O5 glasses, as a metaphosphate structure glass.…”

Various glasses with different compositions (50 -2x)ZnO-xBi2O3-(50 + x)P2O5 (x = 0 -20 mol%) were prepared. This study examined the effect of the structure and properties in phosphate glass system according to the change in Bi2O3 content in ZnO-Bi2O3-P2O5 glass. The structure of the glasses was analyzed by Fourier transform infrared (FT-IR) analysis. The FTIR spectra were recorded in the spectral range from 400 to 1400 cm -1 . The structural investigations based on these spectra showed the rapid depolymerization of the phosphate chains with increasing Bi2O3 content along with the formation of P-O-Bi bonds. The density, glass transition temperature (Tg), molar volume and optical properties of the glasses were determined from the structural changes in the glasses. Tg, density and molar volume increased with increasing in Bi2O3 content in the glass. The optical absorption edge (λ cut-off) and optical band gap (Eg) were determined from the optical transmittance spectra of the polished samples recorded at room temperature, and found to be associated with structural changes occurring in these glasses with increasing Bi2O3 content.

Zirconia was used as a bone substitute, since it has excellent mechanical properties. It is also good bioinert to bone tissue. In this study, we report on zirconia substituted 1393 bioactive glass. In novel melt-derived "1393" Bioactive glass (53 SiO 2 , 6Na 2 O, 12 K 2 O, 5MgO, 20CaO, and 4 P 2 O 5 wt %) with CaO was doped by ZrO 2 for and were melted at 1400°C in alumina crucibles in electric furnace with air as furnace atmosphere. Bioactivity of these samples were analysed by put in the SBF for different time periods. Hydroxy Carbonate Apatite layer was developed and identiûed by FTIR, XRD and SEM. Chemical durability was also determined by weight loss method. Density of the samples were determined and found to increase significantly with increasing amount of (0-2 wt %) zirconia, reason is due to replacement of lighter element of CaO has been replaced by heavier element ZrO 2. Finally, this investigation clearly concluded that ZrO 2 substituted bioactive glass would be potential biomaterials for biomedical applications.
