A Pb-Bi-Sr-Ca-Cu-OXIDE POWDER MIX WITH ENHANCED REACTIVITY AND PROCESS FOR ITS MANUFACTURE
摘要
An Oxide Precursor Powder from the Pb-Bi-Sr-Ca-Cu-O 2223 System can be produced by heat treating powder, produced using the Spray Pyrolysis Process as described in: GB2210605 or EP0681989 between 700 DEG C and 850 DEG C in an atmosphere containing between 0.1 % and 21 % O2. Heat Treatment of the pyrolysis powder under controlled conditions produces a powder with a particular phase composition, that is highly homogeneous and has a small particle size distribution, that is inherently more reactive than powders heat treated in the same way but produced using other processes.
