| Abstract: | BH—A/K glass beads modified by adding different amounts of Al2O3 powder were put into the furnace to burnout the binder(wax removal) at 680 ℃ and spread on Kovar alloy surface at 980 ℃.The influences of Al2O3 amount on the densification of glass beads and wettability between glass and Kovar alloy were studied.The results show that the more Al2O3 adding,the lower densification and the weaker wettability with Kovar alloy are caused after wax removal at the same temperature.To ensure the sealing and intensity between glass and Kovar alloy,the mass fraction of adding Al2O3 is recommended less than 20%. |
