摘要：
The spontaneous reaction synthesis (SRS) of superconductor YBa2Cu3O7 (123) took the shortest time of reaction, less than 5 min, from metals and peroxides as original reaction materials. Chemical stoichiometric ratios of Y:Ba:Cu = 1:2:3 were applied and specimens were subsequently sintered in oxygen with P(O2) = 1 atm at 925-degrees-C for 5 h. X-ray diffraction (XRD), four-wire resistance (rho), magnetic susceptibility measurements (chi) and micro-analysis were conducted to test superconductive properties. The best superconductive properties from the 1:2:3 samples with high-purity single phase of Y1Ba2Cu3O7 were shown by the results to be easily achieved by the SRS process.
