Systematic investigation of sol–gel process in the Y–Ba–Cu–O acetate–tartrate system was
performed using IR spectroscopy. Different values of synthesis parameters (temperature and …

In an attempt to minimize the occurrence of surface nucleation events, the effects of coatings
on the surface of (Y-123) pellets processed by top-seeded melt texture growth processing …

The aim of this paper is to review the different types of grain boundaries found in
YBa2Cu3O7− d superconducting ceramics, which have been investigated over the past …

A new synthetic route is developed to prepare a hydroxide precursor for the superconductor
YBa2Cu3O7− δ. In an inert atmosphere and at low temperature the yttrium, barium and …

The mechanism of the topotactic reaction of superconducting YBa2Cu3O7 thin films with
water vapour is shown to be strongly influenced by the reaction kinetics. At elevated …

Effects of carbon incorporation on the doping state of YBa2Cu3Oy (Y-123) were
investigated. Quantitative carbon analysis revealed that carbon could be introduced into Y …

The paper presents the results of studies on thermogravimetric (TG) characterization of
precursors and Hg-based superconductors synthesized by the sol–gel method. TG …

Abstract YBa 2 Cu 3 O 7− x (123) high-temperature superconducting powders were
synthesized by mixing cost effective Y 2 O 3, CuO and BaCO 3 precursor powders and …

We investigated calcining conditions for YBa/sub 2/Cu/sub 3/O/sub 7-x/(YBCO) films by
metalorganic deposition using trifluoroacetates. We measured residual carbon content by …

Ion beam analysis techniques have been used to probe for carbon contamination in high
temperature superconductor thin films. These techniques provide a powerful tool to detect C …
