Abstract
The method and optimal temperature conditions of preparation of the fl uorine - containing Y1Ba2Cu3O7-deltaFx HTSC ceramics was elaborated. B y X-ray analysis the lattice parameters, unit cell volume and theoreti cal density was determined. The investigation of electrical conductivi ty temperature dependence was carried out. It was find then in Y1Ba2Cu 3O7-deltaF0.1 sample T-c >125 K is stable after 12 cycles of the cooli ng-heating and 5 months exposure on air.
