In the training manual "Processes of receipt, structure and properties of superconductors based on oxide compounds and MgB 2 " on the discipline "Material science of superconductors" considered the stages of development of the theory of high-temperature superconductivity , The classification and level of critical characteristics of superconductors based on HTP and MgB 2 . Methods of obtaining first and second generation HTP and prospects for their application are described. The main focus is on metallurgical studies of composition and structure, as well as ways to increase the current-carrying capacity of superconductors based on HTP and MgB 2 . It is intended for students specializing in the field of physical materials science in the specialty "Physics of metals" . ;Griff:Recommended by UMO "Nuclear Physics and Technologies" as a teaching aid for students of higher educational institutions
