Cu1245 superconductor and preparation method thereof
The invention relates to a Cu1245 superconductor and a preparation method thereof, relates to the technical field of superconducting materials, and is used for solving the problems that a large amount of Cu1223 and Cu1234 symbiotic phases are accompanied in the Cu1245 superconductor synthesized by the existing method, the Cu1245 superconductor cannot be accurately prepared, and the like. According to the method, the Cu1245 superconductor is prepared, CrO3 serves as an oxidizing agent, and an oxygen source is provided for high-pressure sample synthesis; the initial mixed powder and an oxidizing agent are assembled in a layered sandwich mode and sealed in a gold barrel, CrO3 and the initial mixed powder are isolated through silver foil, and the situation that the Cr element enters a sample to pollute the sample is prevented. According to the preparation method, the Cu1245 superconductor which does not contain symbiotic phases such as Cu1234 and the like is prepared by accurately controlling conditions such as reaction pressure, temperature and the like, and a high-quality carrier is provided for subsequent performance test and structure-function relationship research of the Cu1245 superconductor.
本发明涉及一种Cu1245超导体及其制备方法，涉及超导材料技术领域，用以解决现有方法合成的Cu1245超导体中伴有大量的Cu1223和Cu1234共生相，无法精准制备Cu1245超导体等问题。本发明的方法制备了一种Cu1245超导体，本发明的方法以CrO3为氧化剂，为高压合成样品提供氧源；将初始混合粉末与氧化剂采用分层配置的三明治组装，密封在金筒中，其中，CrO3与初始混合粉末中间采用银箔隔离，防止Cr元素进入样品里面造成样品污染。本发明通过精确控制反应的压力、温度等条件，制备出不含Cu1234等共生相的Cu1245超导体，为后续Cu1245超导体的性能测试和构效关系研究提供高质量载体。
