Process for producing moldings tubular made of a material that is superconducting at high temperatures.

摘要

PROCESS FOR PRODUCING TUBULAR PARTS MATERIAL superconductor ELEVATED TEMPERATURE BASED bismuth oxide, calcium, strontium, copper and lead, is introduced into a casting zone broth HOMOGENEOUS MIXTURE OF OXIDES IN RELATION stoichiometric precalculated at a temperature between C. 900 1300 MELROSE AREA TOUR around its axis 15 LEANING According to its variable width. Solidified piece is removed from the casting zone and annealed at a temperature between 700 and 900
