Because Silicon carbide (SiC) ceramics have various excellent properties, the\ndemand for larger and complicated shapes has been increasing. This paper\nintroduces an innovative method that would not require a large furnace, and\nfurther, would minimize the production cost and the thermal history, namely\nthe â??flash-bondingâ? technique. The borosilicate glass with low thermal expansion\ncoefficient, Pyrex glass, was selected as the brazing material. In this\nwork, as-is or surface-oxidized SiC plates were joined using Pyrex glass as\nbrazing material, and the reaction and wetting of Pyrex glass on as-is or surface-\noxidized SiC plate were investigated. It was found that the protective film\nof the surface-oxidized SiC lowered the oxygen partial pressure, and hence,\ngenerated many pores in the interface.
