    • 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 ...

    • Rationalization of hydrothermal synthesis of NaNbO3 by rapid in situ time-resolved synchrotron X-ray diffraction 

      Skjærvø, Susanne Linn; Wells, Kristin Høydalsvik; Sommer, Sanna; Vu, Tuong-Dan; Tolchard, Julian R; van Beek, Wouter; Grande, Tor; Iversen, Bo B.; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2018)
      In situ monitoring of the formation of crystalline phases during conventional hydrothermal synthesis is experimentally challenging. Here, we report an in situ time-resolved synchrotron X-ray diffraction study during ...
