Method for connecting silicon carbide ceramics through calcium oxide/aluminum oxide-based solder
The invention relates to a method for connecting silicon carbide ceramics, in particular to a method for connecting silicon carbide ceramics through calcium oxide/aluminum oxide based solder. The invention aims to solve the technical problem of poor joint structure and performance stability of a fuel cladding material SiC ceramic connection technology in a nuclear reactor at present. According to the CaO/Al2O3 (CA)-based glass ceramic solder, the CaO/Al2O3 (CA)-based glass ceramic solder is designed, and when the CaO/Al2O3 (CA)-based glass ceramic solder is applied to a SiC connection technology in a nuclear irradiation environment, the CaO/Al2O3-based glass ceramic solder which is simple in component and stable in performance has an application prospect. On the basis of CaO/Al2O3 glass solder, proper SiC powder with excellent radiation resistance is added, so that the thermal expansion coefficient of the solder is reduced and is matched with that of SiC ceramic, and a more excellent radiation-resistant joint can be formed.
一种氧化钙/氧化铝基焊料连接碳化硅陶瓷的方法，涉及一种连接碳化硅陶瓷的方法。本发明是要解决目前核反应堆中燃料包壳材料SiC陶瓷连接技术接头组织和性能稳定性差的技术问题。本发明设计了CaO/Al2O3(CA)基微晶玻璃焊料，在应用于核辐照环境下SiC连接技术中，成分简单，性能稳定的CaO/Al2O3基玻璃焊料具有应用前景。在CaO/Al2O3玻璃焊料的基础上加入适当的耐辐照性能优越的SiC粉末，以降低该焊料的热膨胀系数，使之与SiC陶瓷的热膨胀系数相匹配，可以形成更为优秀的耐辐照接头。
