The electrical properties of dense nanocrystalline ceramics with an average grain size of 35 nm were investigated by impedance spectroscopy and compared with a coarsened material with micron size grains. The nanocrystalline ceramics show an uncommon domain of ionic conductivity at high oxygen pressures and a steep increase of electronic conductivity at low oxygen pressures. These results are discussed in terms of defect chemical models. The enthalpy of reduction of the nanocrystalline was deduced to be significantly lower than that of the coarsened material. This may be related to lower defect formation energies at interface sites.
About Me
Philippe Knauth has been a Professor of Materials Chemistry at Aix Marseille University (AMU) since 1999. He was a post-doctoral fellow (CNRS, Centre de Thermodynamique et de Microcalorimétrie) from 1987 to 1989, a laboratory head (Bayer, Pigments and Ceramics Division) from 1989 to 1990, and a CNRS researcher (“Chargé de Recherche“) from 1990 to 1999. He obtained a Diploma in Chemistry (Dipl.-Chem., Saarland University) in 1984, a PhD in Physical Chemistry (Dr. rer. nat., Saarland University) in 1987, and a Habilitation in Materials Science (Aix Marseille University) in 1996. He obtained the CNRS Bronze Medal in 1994, a Silver Medal from Warsaw University of Technology in 2015, the Grand Prize SCF-PACA/SCI Liguria/Piemonte in 2021, and has been a Fellow of the French Chemical Society since 2018.
