摘要：

It was demonstrated that superconducting 124 material can be successfully prepared by using oxide-nitrate-mixtures or nitrate-mixtures with short reaction times at normal oxygen pressure conditions. Small quantities of CuO, BaCuO2 and Y2BaCuO5 could be detected as phase impurities by X-ray diffraction. The best quality samples were prepared using freeze-dryed nitrate solution with Na2CO3 as an accelerator. The amount of impurity phases in these samples was near the detection limit of X-ray diffractometry.
