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