Abstract
Via in situ electrical property measurements (conductivity, Seebeck coefficient) over the temperature range 500–800 °C and oxygen partial pressure range 10-4-1 atm, the equilibrium transport properties and stability range of YBa2Cu408were determined. YBa2Cu408 behaves like the intrinsically mixed-valent compound, magnetite (Fe304), with small variations in electrical properties with changes in oxygen partial pressure. The decomposition boundary to YBa2Cu306+y(or YBa2Cu3.507.5±z) and CuO occurs at log(po2, atm) = -1.24 x 104/T(K) + 11.01(773 < T(K) < 1073).
