Thermal stability of porous sol-gel phosphosilicates and their surface area stabilisation by lanthanum addition [PDF]

Materials Letters, 2016
The thermal stability of porous sol-gel phosphosilicates was studied by comparing the textural features upon calcination between 400 and 550 °C. A significant loss of surface area and pore volume were observed; the first is due to thermal coarsening of the nanoparticles, and the pore volume reduction was ascribed to sintering of the most external ...

Scaling inhibition by sol-gel phosphosilicate hybrid films: Influence of doping Cu2+ and Zn2+ cations

Surface and Coatings Technology, 2022
In this work, the scaling protection performance of Zn 2+ and Cu 2+ , added to a phosphosilicate hybrid sol-gel coating and applied on both carbon and stainless steel surface, was evaluated for the first time in a solution containing initially 200 mg.L-1 of Ca 2+ (corresponding to a water hardness of 50 °F) at 30 °C. Inhibition efficiency was estimated

Phosphosilicate Gels as a Solid State Proton Conductor at Medium Temperature and Low Humidity.

Journal of the Ceramic Society of Japan, 2002
Phosphosilicate (P2O5-SiO2) gels with a P/Si molar ratio of 1.0 heat-treated at 150°C were found to retain a high conductivity of 1.5×10-2S·cm-1 even after holding at a temperature of 130°C at a relative humidity of 0.7% for about 400 min. On the other hand, the conductivity of the porous silica gels impregnated with 5M H3PO4 largely decreased from 1 ...

Role of P2O5 on Protonic Conduction in Sol-Gel-Derived Binary Phosphosilicate Glasses.

Journal of the Ceramic Society of Japan, 1999
Sol-gel derived P2O5-SiO2 glasses were studied and a remarkable improvement in protonic conduction was observed by increasing the P2O5 content. This was attributed to (1) the variation in glass structure including the reduction of the degree of cross-linking skeleton and the increase of specific surface area of glass due to the non-bridging oxygen (P=O)
