“…Here, the measurement technique by the gas equilibrium method is explained. A thermo-gravimetry and differential thermal analysis system (TG-DTA) was put in glove box and used to measure oxygen potential (Kato et al, 2005(Kato et al, , 2009b(Kato et al, , 2011b(Kato et al, , 2011c. The oxygen partial pressure of the flowing gas was monitored at the inlet and outlet of the apparatus using stabilized zirconia oxygen sensors.…”
