摘要
本文利用固相反应成功地制备出直径Φ100mm,厚度5mm的高质量超导靶材,超导靶材零电阻温度为91K,同时对靶材原粉的要求和制靶工艺进行了分析。X射线衍射进行物相定性分析,扫描电镜进行形貌现察。用此靶材制备的超导薄膜,其零电阻温度在90K,临界电流密度大于106/cm2,并用于制备超导电子器件。
We have prepared high-quality superconducting target with 100mm in diameter and 5mm in depth by soid-state reaction, The zero-resistance temperature of superconductor is 91k, the require of powders and technology of target heve been analysed. X-ray diffraction is used for analysing, electronic-microscope sanning is used to observ superconductor. The target are used to prepare the superconducting film, the zero-resistance temperature of films is 90k, the maximum critical current density has reached 106A/cm2. they can be used to make a various of superconducting electroic elements.
