SiO2-CaO-Al2O3 Glass Solder for Joining of Al2O3 to Al2O3

open access: yesHigh Temperature Materials and Processes, 1998
To utilize glass as a solder for joining of ceramics, the joining of Al 2 O 3 to Al 2 O 3 by glass solders with the compositions (mass %) of 33SiO 2 -34CaO-33Al 2 O 3 and 50SiO 2 -38CaO-12Al 2 O 3 has been investigated. The thermal expansion of these glasses and the wettability between glasses and alumina have been measured to confirm the ...

SO2 Reactions over γ-Al2O3,Pt/γ-Al2O3,Sn/γ-Al2O3 and Pt–Sn/γ-Al2O3

open access: yesCatalysis Communications, 2001
Abstract Platinum and Platinum–tin bimetallic catalysts supported on alumina were prepared by co-impregnation of both metallic precursors on the support and used as catalysts for the oxidation of SO 2 . Platinum dispersion was determined by means of H 2 –O 2 titration.

Atomic layer deposited films of Al2O3 on fluorine-doped tin oxide electrodes: stability and barrier properties

open access: yesBeilstein Journal of Nanotechnology, 2021
Al2O3 layers were deposited onto electrodes by atomic layer deposition. Solubility and electron-transport blocking were tested. Films deposited onto fluorine-doped tin oxide (FTO, F:SnO2/glass) substrates blocked electron transfer to redox couples ...
