Method for connecting SiC ceramic material by using calcium oxide/aluminum oxide/silicon dioxide/lithium oxide glass solder
The invention discloses a method for connecting SiC ceramic materials by using calcium oxide/aluminum oxide/silicon dioxide/lithium oxide glass solder, and relates to a method for connecting SiC ceramic materials by using glass solder. The invention aims to solve the technical problems that the connection of SiC ceramics needs high-temperature and high-pressure conditions under the current nuclear reactor service condition, and the joint performance and the radiation resistance are poor. According to the method, the mechanical property of the joint can be improved, meanwhile, the reliability of the SiC ceramic welding structural part in the nuclear irradiation service environment can be improved, and the welding structure is expected to be used in the nuclear power field. The glass solder connecting method has the advantages that the glass solder connecting method is easy to use, connection can be achieved under the conditions of no pressure, atmosphere and relatively lower connecting temperature of 1200-1280 DEG C, the solder can form a glass ceramic welding seam with high crystallization rate in situ in the welding heat cycle, and the mechanical property and the radiation resistance of a connector can be remarkably improved.
