用MOCVD法在Ag基体上以～15cm/h的带速连续制备YBCO超导带.在800—850℃之间沉积的样品均呈强烈c-轴取向;而在750-800℃间,c-轴取向明显减弱.前者为不规则排列的大片状晶结构,而后者为不规则排列的小棒状晶和发育不良的片状晶,或者为小粒状晶堆集.所制样品的Jc(78K,0T)一般在0.5—1×104A/cm2之间,最好的达到1.4×104A/cm2.

A new hot-wall quartz MOCVD reacter has been developed, which overcomes the drawback of foregoing decomposition of metalorganic source gases and suits for continuous preparation of YBCO superconducting tape on metal substrate. Experiments on preparation o
