【Abstract】 The structure, morphology and properties of high temperature superconductor have been investigated. The composition, structure and morphology were studied by using SEM, TEM, EDS and SAED etc. R～T and X～T relations of the sample were measured with the zero resistance temperature T_C0≈91 K and the all diamagnetic temperature being 88K. Then, the properties of the superconducting compound YBa₂Cu₃O_7-x were discussed initially.更多还原
