利用活性硬焊料或钎焊料接合陶瓷体的方法、具有彼此接合的至少两个陶瓷体的组件，特别是压力测量单元
摘要：
本发明涉及一种组件，其包括：利用活性硬焊料或钎焊料(5)的接缝连接的第一陶瓷体和第二陶瓷体(1，2)，其中所述活性硬焊料或钎焊料(5)在连续主体积上均分，所述主体积包括至少50％的所述接缝体积，具有有液相线温度Tl(CH)的平均组成CH。其中，根据本发明，所述接缝的边缘区域具有有液相线温度Tl(CR)的平均组成CR，所述接缝的边缘区域接触所述陶瓷体(1，2)中的至少一个，所述液相线温度Tl(CR)比所述主体积的平均组成CH的液相线温度Tl(CH)高至少20K、优选地至少50K且特别优选地至少100K。
摘要（英）：

The invention relates to an assembly comprising: a first and a second ceramic body (1, 2) connected by means of a joint that has an active hard solder (5), said active hard solder (5), when averaged over a cohesive main volume comprising at least 50% of the volume of the joint, has an average composition CH with a liquidus temperature TI(CH). According to the invention, a border region of the joint, said region touching at least one of the ceramic bodies (1, 2), has an average composition CR with a liquidus temperature TI(CR), said temperature lying no less than 20 K, preferably no less than 50 K, and especially preferably no less than 100 K above the liquidus temperature TI(CH) of the average composition CH of the main volume.
