Abstract:
Objective: To investigate the influence of repeated infiltrating on the microstucture of In-Ceram alumina substrate. Methods:6 disks of aluminum oxide with the height of 3 mm and diameter of 12 mm were perpared and infiltrated with infiltrating glass for 0～5 times for each disk respectively.The fractured surfaces of the samples were observed by scanning elctron microscope. Results:After sintering,a net -shaped porous coping of alumina was formed. The glass infiltration resulted in a dense ceramic mass. The porous coping matrix was infiltrated with low-viscosity glass in void.3-time-infiltration resulted in the best results. Conclusion: With repeated infiltrating firing,the micro-stucture of In-Ceram alumina substrate may become a dense mass.
