    • A fast, low temperature synthesis method for hexagonal YMnO3: Kinetics, purity, size and shape as studied by in situ X-ray diffraction 

      Marshall, Kenneth; Blichfeld, Anders Bank; Skjærvø, Susanne Linn; Grendal, Ola Gjønnes; Van Beek, Wouter; Selbach, Sverre Magnus; Grande, Tor; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2020)
      The reaction mechanisms, phase development and kinetics of the hydrothermal synthesis of hexagonal‐YMnO3 from Y2O3 and Mn2O3 using in situ X‐ray diffraction are reported under different reaction conditions with temperatures ...

    • Kinetics during hydrothermal synthesis of nanosized KxNa1-xNbO3 

      Skjærvø, Susanne Linn; Wells, Kristin Høydalsvik; Van Beek, Wouter; Grande, Tor; Einarsrud, Mari-Ann (Journal article, 2018)
      Hydrothermal synthesis is an efficient method of making nanosized functional oxide materials, and it has also been used to synthesize KxNa1−xNbO3 solid solution, a promising lead-free piezoelectric material. However, the ...

    • Understanding the Hydrothermal Formation of NaNbO3: Its Full Reaction Scheme and Kinetics
