METHOD OF PREPARING SUPERCONDUCTIVE MATERIAL Russian patent published in 1995 - IPC

Abstract SU 1793669 A1

FIELD: chemical technology. SUBSTANCE: method involves mixing of component containing lanthanide, among them scandium and yttrium. One of sulfide of the latter, and also copper oxide, alkaline-earth oxide or peroxide were used also. Combustion process is initiated in the presence of oxidizing agent (ammonium perchlorate, alkaline, alkaline-earth metal and/or iodine pentoxide), and process is performed under pressure 0.06-8.0 MPa. Method ensures to prepare superconductive material showing regulating porosity and high mechanical strength. EFFECT: improved method of preparing. 1 tbl
