Ti element is found to aggregate, forming an ultra-fine reaction layer in the active filler metal-ceramic joint after 260℃/24hr aging treatment. Two different-color intermetallic compounds are observed in the interface of active filler metal-copper. One is Cu6Sn5 , which is closer to active filler metals;the other is Cu3Sn, which is closer to the copper substrate.

接合后之试片，经260℃/24hr时效反应后，发现Ti元素聚集於焊料与陶瓷界面处形成一层极薄的反应层且发现在焊料与铜之反应界面有了明显颜色不同之两层介金属层生成，靠近焊料端的介金属层为Cu6Sn5，Cu片端的是Cu3Sn；而Cu6Sn5化合物从原本未时效10μm成长为25μm。
