| titleOfInvention | Method for producing high Tc superconductor containing thallium under gas flow atmosphere |
| abstract | (57) [Summary] A method for producing a high Tc superconductor containing thallium, calcium, barium and copper, and further optionally containing lead and / or strontium, comprising a thallium-free precursor as a first step. Produced in a reaction process, followed by mechanically pulverizing and heat treating for 3 hours or more at a temperature in the range 700-950 ° C. Then the mixture is cooled to ambient temperature and ground again. Finally, heat treatment is performed in a pure oxygen flow at a temperature of 400 to 500 ° C. Thallium - free precursor, then the powdered with Tl 2 O 3, is into shaped articles if desired, then fired oxidatively under gas atmosphere. |
