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° C. and 850° 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.
