Manufacture technology of ultradispersive powder (UDP) of YBa2Cu3O7-x and high-temperature superconducting (HTSC) ceramic materials is described. Synthesis of YBa2Cu3O7-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 (jc=103-104 A/cm2, Tc=95 K, ΔTc=1 K). The application of Cu UDP reduces the temperature and duration of synthesis of YBa2Cu3O7-x HTSC powder.
