Abstract
It is proposed to use mixed precipitation of Y(NO3)(3) and Cu(NO3)(2) with aqueous KOH to increase the mass of single-phase Yba(2)Cu(3)O(7-g amma) powder without adversely affecting the electrophysical parameter s. The barium is added as an aqueous solution of Ba(OH)(2), and the po wder is produced by a two-stage method. The parts of the powder are ag glomerates made up of finely divided powder active in sintering. The t echnological features of the powder have been examined and the moldabi lity limits have been defined.
