FIELD: electricity; chemistry.
SUBSTANCE: manufacturing method of material from oxide superconductor includes: (a) powder of initial materials dissolution in solution of inorganic acid or in alkaline solution, (b) removing of solvent by means of solution pulverisation in the first gaseous medium with powder receiving, containing a dollop of substance for oxide superconductor composition, and (c) powder cooling in the second gaseous medium, in which it is introduced cooling gas. In this method carbon dioxide concentration in the second gaseous medium is lower then in the first gaseous medium, which contains removed solvent components. Nitrogen oxide concentration in the second gaseous medium is lower then in the first gaseous medium, which contains removed solvent components. Water vapour concentration in the second gaseous medium is lower then in the first gaseous medium, which contains removed solvent components.
EFFECT: increasing of density and purity of oxide superconductor.
