A sal—gel method of preparing fine-particle superconducting oxide YBa2Cu307-xwas developed. Single-phase superconducting oxide YBa2Cu307 formed at temperatures as low as 750 °C. The particle size obtained by this method was found to be ≤0.2μm. Pellets sintered from these sol—gel powders exhibited very sharp resistivity drops at Tc= 90 °C with a ΔTc of ~3°K.
