−13 atm. In addition to this pressureless quench, one sample was rapidly cooled from 1100 °C and 8×10
−14 atm while subjected to compressive stress of 30 MPa. The samples are studied by a range of structural, elemental and chemical analysis techniques, as well as microscopy. In addition, the material is subjected to isothermal thermogravimetric and electrical conductivity measurements as a function of oxygen partial pressure. These results are analyzed in view of obtaining more information about the mechanisms responsible for the creep behavior of this compound in controlled oxygen atmosphere.
