具有彼此接合的陶瓷体的组件、其压力传感器及制造方法
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(CM)的平均组成CM。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(CE)的平均组成CE，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(CE)比所述主体积的平均组成CM的液相线温度Tl(CM)高至少20K、优选地至少50K且特别优选地至少100K。
摘要（英）：

An assembly, comprising: a first ceramic body and a second ceramic body connected by means of a joint of an active hard solder, or braze, wherein the active hard solder, or braze, averaged over a continuous main volume, which includes at least 50% of the volume of the joint, has an average composition CM with a liquidus temperature Tl(CM). An edge region of the joint, which contacts at least one of the ceramic bodies, has an average composition CE with a liquidus temperature Tl(CE), which lies not less than 20 K, preferably not less than 50 K, and especially preferably not less than 100 K above the liquidus temperature Tl(CM) of the average composition CM of the main volume.
