摘要
用混合熔烧的方法，制备出一种氧化物封接料．该封接料能在７００℃下对氧化铝瓷与铜及铜合金进行气密性封接．在封接中，只需将封接料涂在陶瓷体的封接面，套上金属件，在马弗炉中以５℃／ｍｉｎ升温到７００℃后保温１０ｍｉｎ即可．对封接体所作的拉伸强度和气密性质量检测表明，封接界面的抗拉强度高于陶瓷本体强度，界面对空气的漏率小于１．４×１０－９Ｐａｍ３／ｈ，满足工业部门对封接质量的要求．
A bonding material for brazing ceramic to metal was prepared and the corresponding bonding technology were developed. The examination for the properties of the interface between ceramic and metal showed that the tensile strength of the joint is higher than that of ceramics and the leaking rate to air on the joint is less than 1 4×10 -9 Pa·m 3/h. This technology can be used in a wide variety of industries to form a hermetic ceramic metal jointing.
