Abstract

Different mechanical testing methods have been used to assess the elastic behavior of the mixed ion electron conducting perovskite Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF). Although the main aim is the comparison of the testing techniques for ceramic material in general, experiments have been performed at RT and up to 900 °C to illustrate the capabilities of the utilized methods for a perovskite with a stiffness anomaly. BSCF specimens in disc shape and tubular geometry provided by different suppliers were tested in biaxial bending by ring-on-ring testing and under uniaxial stress in O-ring and under compression loading. The elastic modulus was determined as a function of temperature up to 900 °C. In addition, the room temperature elastic modulus was measured using depth-sensitive indentation.
