Abstract: Short-duration melting of high-T_c superconducting ceramics of CO₂ laser radiation, in combination with a short heat treatment, produced a denser fine-grained structure (grain size 2 — 3 μm) both in the original Bi(2223) ceramic and in a doped material. The resultant structure contributed to a considerable increase in the critical current of the superconductors.
