Research abstract
WE PROPOSE TO MEASURE PHASE EQUILIBRIA IN THE THALLIUM SUPERCONDUCTING SYSTEM. THE GOAL IS TO UNDERSTAND THE COMPLEX SOLID-LIQUID-VAPOR EQUILIBRIA THAT GOVERN CRYSTAL GROWTH OF THE FAMILY OF SUPERCONDUCTORS - TL2BA2CA(N-1)CU(N)O(4+2N)(N=2,3). THIS STUDY WILL INVOLVE EXPOSURE OF FILMS AND POWDER MIXTURES OF KNOWN COMPOSITION TO CONTROLLED OVERPRESSURES OF THALLOUS OXIDE (TL2O) AND OXYGEN VAPOR AT HIGH TEMPERATURE (600 - 950 DEGREES CENTIGRADE) FOLLOWED BY QUENCHING. THE COMPOSITION AND MICROSTRUCTURE OF QUENCHED SAMPLES WILL BE EXAMINED TO IDENTIFY THE EQUILIBRIUM HIGH TEMPERATURE PHASES. IN THIS MANNER THE LIQUIDUS AND SOLIDUS TEMPERATURES, EQUILIBRIUM TL2O AND O2 OVERPRESSURES, AND STABLE PHASES WILL BE DETERMINED IN THOSE REGIONS OF COMPOSITION THAT ARE IMPORTANT FOR TBCCO THIN FILM AND CRYSTAL GROWTH. ADDITIONAL INFORMATION ON PHASE CHANGES WILL BE GAINED BY DIFFERENTIAL THERMAL ANALYSIS (DTA) USING SEALED GOLD AMPOULES TO CONTROL THALLIUM VOLATILITY
