Abstract

Manufacture technology of ultradispersive powder (UDP) of YBa₂Cu₃O_7-x and high-temperature superconducting (HTSC) ceramic materials is described. Synthesis of YBa₂Cu₃O_7-x is carried out by the solid-phase method from the stoichiometric composition of Y₂O₃, BaCo₃, CuO using the standard HTSC ceramic technology. Dispersivity of standard components is 5-50 μm and dispersivity of Cu UDP 0.05-1 μm. The technology supposed allows to obtain monophase dense textured ceramic materials with the high critical parameters (j_c=10³-10⁴ A/cm², T_c=95 K, ΔT_c=1 K). The application of Cu UDP reduces the temperature and duration of synthesis of YBa₂Cu₃O_7-x HTSC powder.
