The EDT A gel processing route has been used to
produce (2223) BSCCO superconductiong oxides. Gel -
processed (2223) BSCCO material was sintered in air or
oxygen to produce specimens for transition temperature
determination; the same specimens were characterised by
high re.'ioultion transmission electron microscopy fitted with
EDAX analysis to yield information about homogeneity,
microstructure and identification of any grain boundary
phases that may be present. Electrical resistivity

to allow the superconducting transition temperature to be
determined as a function of sintering atmosphere.
Transition to a superconducting state at I 10k was observed
in samples sintered and quenched in air
