Solid state 29Si and 31P NMR study of gel derived phosphosilicate glasses

Journal of Materials Chemistry, 2001
Solid state 29Si and 31P MAS NMR have been used to investigate the microstructural changes occurring in phosphosilicate gels during their conversion from a gel to the corresponding gel-derived glasses by heating. The studied gels have the molar compositions 10P2O5·90SiO2 and 30P2O5·70SiO2.

Thermal evolution of sol–gel-obtained phosphosilicate solids (SiPO)

Journal of Non-Crystalline Solids, 2001
Abstract Amorphous phosphosilicate solid with P–O–Si linkages was obtained by a sol–gel process starting from tetraethoxysilane (TEOS) and H 3 PO 4 . The evolution of the structure of as-prepared gel was investigated as a function of the heat-treatment temperatures, by scanning electron microscopy (SEM), X-ray powder diffraction (XRD), diffuse ...

Proton conductivities of sol–gel derived phosphosilicate gels in medium temperature range with low humidity

Solid State Ionics, 2002
Abstract Phosphosilicate gels derived from tetraethoxysilane (TEOS) and H 3 PO 4 with a P/Si mole ratio of 1.0 retained a high proton conductivity of 1.5×10 −2 S cm −1 during the keeping at 130 °C and 0.7% relative humidity for about 400 min. The presence of water molecules with good affinity for gel matrix, which was confirmed from the thermal ...

3D printed Er3+/Yb3+ co-doped phosphosilicate glass based on sol-gel technology

Journal of Non-Crystalline Solids, 2020
Abstract We demonstrate a method to manufacture Er3+/Yb3+ co-doped phosphosilicate glass by the digital light processing (DLP) 3D printing based on sol-gel technology. The sol-gel technology was used to fabricate the rare earth ions doped photocurable printing ink to achieve excellent fluidity, tunable composition and uniform component distribution ...

Structural characterization of some sol–gel derived phosphosilicate glasses

Journal of Molecular Structure, 2015
Abstract A comparative study of three phosphosilicate gels of the 90SiO 2 –10P 2 O 5 composition obtained from tetraethoxysilane and three phosphorous precursors: triethylphosphate (TEP), triethylphosphite (TEPI) and H 3 PO 4 is performed. 29 Si and 31 P Magic Angle Spining NMR, X-ray Photoelectron, X-ray Fluorescence and Raman spectroscopies as ...
