METHOD FOR GENERATING SUPERIORITY AT TEMPERATURES HIGHER THAN THE NITRATED TEMPERATURE OF NITROGEN (77K) IN OXIDIC COMPOUNDS

摘要

The essential features of the invention consist in the fact that blanks made of certain metal oxide complex compounds prepared by known processes are partially or completely converted into a phase by laser irradiation in the last processing step, which is superconducting at temperatures above 77 K (so-called high-Tc superconductor) ). As a result of the laser irradiation, the blank is heated as a whole or selectively, wherein the physico-chemical transformations leading to the formation of the superconductive phase take place under the surrounding oxygen-containing atmosphere. By suitable movement of the laser beam with the blank fixed or by suitable movement of the blank with the laser beam fixed, it can be achieved that selected areas of the blank are brought into the superconductive phase, so that production of superconducting geometric structures is possible {high-temperature superconductivity; Laser irradiation; superconducting structures; Metal complex compounds; Structural transformation; Heat Treatment; Structuring; Phase transformation; selective heating; superconducting compounds}
