Essay

The thesis is developed to the investigation of stabilization methods of superconductive properties of HTS compounds. For the first time series of composite samples based on superconductive ceramics YBa2Cu3O7-х and Bi2Sr2CaCu2Ox with organic and inorganic composite additives have been synthesized. The doping influence on HTS properties has been investigated. The stabilizing effect of the composite additives in chemical degradation process of superconductive ceramics have been investigated. Superconductive samples series (Pb0,63Cu0,27)Sr2(Ca0,21Ln0,79)Cu2O7-d have been synthesized. The influence of the rareearth elements on HTS samples prorerties have been investigated. Theoretical analyses of (Pb1-yMy)Sr2(Ca1-xRx)Cu2O7-d (M - metal, R - rareearth element) superconductive properties dependence from chemical composition has been made.
