    • Formation mechanism and growth of MNbO3,M=K, Na by in situ X-ray diffraction 

      Skjærvø, Susanne Linn; Sommer, Sanna; Nørby, Peter; Bøjesen, Espen Drath; Grande, Tor; Iversen, Bo B; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2017)
      Hydrothermal synthesis is a well-established method to produce complex oxides, and is a potential interesting approach to synthesize stoichiometric lead-free piezoelectric K0.5Na0.5NbO3. Due to challenges in obtaining the ...

    • Revealing the Slow Decomposition Kinetics of Type-I clathrate Ba8Ga16Ge30 

      Reardon, Hazel; Blichfeld, Anders Bank; Kasai, Hidetaka; Yin, Hao; Bøjesen, Espen Drath; Iversen, Bo B (Journal article; Peer reviewed, 2017)
      Inconsistencies in high temperature thermoelectric property measurements of Ba8Ga16Ge30 have prompted our study on the thermal stability of this heavily studied inorganic clathrate. Using X-ray diffraction, thermal analysis, ...
