Bonding method for aluminum oxide ceramics
The invention relates to a bonding method for aluminum oxide ceramics. Polyborosilazane (PSNB) is adopted as a binder between aluminum oxide ceramics; an additive needs to be added in modification research of a high-temperature binder; actually, Si and B elements are added, and the polyborosilazane (PSNB) contains the two elements. The PSNB can be solidified at 120 DEGC for two hours; the curing temperature is low; the additive does not need to be added; and the high-temperature bonding target can be reached by heat treatment in air. The binder used by the invention has high bonding strength at 1400 DEG C and 1500 DEG C, so that the operating requirements of the binder at a high temperature are reached. The bonding method is a preparation technology capable of bonding the ceramics with low roughness on the surface and meeting the strength requirements, and is relatively low in cost, and relatively simple and efficient.
