| Abstract: | In this paper it is reported that the instability of YBa_2Cu_3O_7 phase with thesuperconductivity about 90 K was discovered when stored in the atmosphere.By themethod of powder X-ray diffraction,it can be confirmed that BaCO_3 could formthrough the reaction between YBa_2Cu_3O_7 and CO_2 under the ambient temperatureand pressure. |
