METHOD FOR MANUFACTURE OF TUBULAR SHAPED PARTS FROM HIGH-TEMPERATURE SUPERCONDUCTING MATERIAL Russian patent published in 1998 - IPC

Abstract RU 2104822 C1

FIELD: methods for manufacture of tubular shaped parts from high-temperature superconducting materials based on oxides of bismuth, calcium, strontium, copper and, in particular case, lead. SUBSTANCE: method includes preparation of homogeneous melt of oxides with preset stoichiometry, pouring of it with temperature of 900-1300 C into mold which is rotated at speed of 200-1500 rpm round axis inclined to horizontal at an angle of not less than 15 deg. Solidified shaped part is withdrawn from mold and fired for 4-150 h at 700-900 C in oxygen-containing atmosphere. EFFECT: higher efficiency. 7 cl, 5 dwg, 3 tbl
