解釋
活性鎢-
W - cu composites are usually fabricated by infiltration - sintering porous tungsten compacts with molten copper or by liquid - phase sintering w - cu powder compacts
W - cu復合材料通常採用粉末冶金熔滲燒結或液相燒結法制取。 -
Ysialon and casialon glasses also form at the interface. if 0. 45 % wt sio2 is added in the paste, the tungsten paste has low sheet resistance and matching shrinkage of a1n green - sheet bodies. at this concentration of sio2 in the paste, a1n substrate is little porous at interface
在陶瓷介質和導帶漿料之間的界面位置,有sio _ 2 、 aln ,以及aln的添加劑cao和y _ 2o _ 3存在,它們四種單質材料發生反應,在界面位置形成ysialon , casialon玻璃相和casialo和ysio的晶相,提高了焊盤的附著力。
