The paper uncovers an underlined mechanism of joining Yttrium Iron Garnet (YIG) and Magnesium Titanate Ceramic (MTC) with a bismuth-based glass braze. The proposed joint design has not been investigated until present. The central hypothesis is as follows. The brazed bismuth-based glass microstructure and the resulting mechanical strength of a YIG/MTC joint design support favorably a good bonding of the interface domains. The supporting evidence includes the following: (i) the bismuth-based glass features good wettability on YIG and MTC, (ii) the sequence of the coefficients of thermal expansions (YIG, bismuth-based glass, MTC) is in a favorable succession. The study reveals that the interface reactions form: (i) a lamellar phase and YBO3 whiskers at the YIG/Bi25 interface, (ii) both MgFe2O4, and Bi4Ti3O12 whiskers in addition to Zn2Ti3O8 reaction layer at the MTC/Bi25 interface, and (iii) Fe2O3 phase along the brazing seam. The mechanical integrity of joints has been studied as well.

铋基玻璃钎焊的YIG / MTC接头的新设计

该论文揭示了用铋基玻璃钎焊将钇铁石榴石(YIG)和钛酸镁陶瓷(MTC)连接在一起的强调机制。直到现在为止,尚未对拟议的联合设计进行调查。中心假设如下。钎焊的铋基玻璃微结构以及YIG / MTC接头设计所产生的机械强度有利地支持了界面域的良好粘合。支持的证据包括:(i)铋基玻璃在YIG和MTC上具有良好的润湿性;(ii)热膨胀系数的序列(YIG,铋基玻璃,MTC)顺序良好。研究表明,界面反应形式为:(i)层状相和YIG / Bi25界面处的YBO 3晶须,(ii)MgFe 2除了在MTC / Bi25界面处的Zn 2 Ti 3 O 8反应层之外,还包括O 4和Bi 4 Ti 3 O 12晶须,以及(iii)沿钎缝的Fe 2 O 3相。接头的机械完整性也已被研究。
