Abstract

The decomposition of EDTA gel precursors for BSCCO superconductor manufacture has been studied using STA (TG/DTA) and dilatometry in conjunction with FTIR. The thermoanalytical data are discussed in relation to the sequence of phase formation necessary for the production of the 2223 BSCCO superconducting phase. The effects of substitution of Pb for Bi on the temperatures of formation of the superconducting phases is also discussed. STA has also been carried out under varying oxygen partial pressures to determine the effects of oxygen pressure on the formation and decomposition of the phases involved in the production of the 2223 compound.

Zusammenfassung

Mittels STA (TG/DTA) und Dilatometrie wurde in Verbindung mit FTIR die Zersetzung von EDTA Gelpräkursoren für die Fertigung von BSCCO Supraleitern untersucht. Die thermoanalytischen Daten wurden unter dem Aspekt der Abfolge der Phasenbildungsprozesse diskutiert, welche für die Herstellung der supraleitenden Phase 2223 BSCCO notwendig ist. Auch der Einfluß des Ersatzes von Bi durch Pb bei den Temperaturen für die Bildung der supraleitenden Phase wurde diskutiert. STA wurde auch bei verschiedenen Partialdrücken für Sauerstoff durch geführt, um den Einfluß des Sauerstoffdruckes auf die Bildung und Zersetzung der bei der Herstellung der Verbindung 2223 auftretenden Phasen zu bestimmen.
