过氧化物BaO_2高频熔融快速制备YBCO超导材料

To Prepare the Ceramic Superconductor in the Short Time with the Superoxid BaO_2 by the High Freqency Melting Method

高温陶瓷超导材料是按一定成份比 ,包括氧化物和盐类的混合 ,经过烧结并在氧气气氛下经过长时间的退火 ,才能制成。一般都需要花费十几个小时乃至几十个小时。本文介绍一种用过氧化物BaO2 来替代BaO或BaCO3经过高频熔融加热的方法 ,在两个小时左右就可制备YBaCuO超导材料 ,提供了一种缩短制备超导材料时间的方法。

The method of preparing high temperature ceramic superconductor in the short time has been used with the superoxid BaO-2 by the frequency zone melting in this paper. There are probably two reasons for saving time in preparing high temperature ceramic superconductor:First, BaO or BaCO-3 is replaced with the superoxid BaO-2. Second, the method is in terms of the frequecy zone melting.
