Abstract

A sol-gel method of preparing fine-particle superconducting oxide YBa₂Cu₃O_7−x was developed. Single-phase superconducting oxide YBa₂Cu₃O_7−x formed at temperatures as low as 750°. 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 T_c = 90 °C with a Δ_c of ∼3°K.
