在研究 Ti-Ag-Cu 法封接区域物相时,我们发现并首次确定在陶瓷界面上形成2.5μ的“过渡层”——Cu_2(Ti,Cu)_4O。对该关键物相的氧源研究是封接机理的一个重要组成部分和关键所在。目前,国内、外关于活性法氧源的研究还没能取得成熟的看法。问题在于:没有取得充分的实验证据。氧的几种可能来源:分析其氧源,从封接的陶瓷中找,可能有:(A)吸附和气相;(B)玻璃相;(C)α-Al_2O_3。另外,可能还有(D)真空炉内残留气体;(E)金属件和焊料;(F)炉内各种金属件(包括炉丝、炉体等)。实验及其结果:为了确定主要氧源,开展了下列实验并
In the study of the phase of Ti-Ag-Cu method, we found and determined for the first time that a 2.5μ “transitional layer” -Cu_2 (Ti, Cu) _4O was formed on the ceramic interface. The study of the oxygen source of this key phase is an important part of the sealing mechanism and the key point. At present, the domestic and foreign research on the active oxygen source has not yet achieved a mature view. The problem is: There is no sufficient experimental evidence. Several possible sources of oxygen: Analysis of its oxygen source, from the seal of the ceramic to find, there may be: (A) adsorption and gas phase; (B) the glass phase; (C) α-Al_2O_3. In addition, there may be (D) residual gas in the vacuum furnace; (E) metal parts and solder; (F) furnace various metal parts (including furnace, furnace, etc.). Experiments and Results: In order to identify the major source of oxygen, the following experiments were carried out
