DESCRIPTION:Speakers: Robert Aughterson (ANSTO)\nThe structure types withi
 n the Ln2TiO5 (Ln = lanthanides) system have similarities with many of the
  proposed phases within the titanate ceramic waste-form Synroc. Certain co
 mpounds might also be suitable for inert matrix fuel applications. Previou
 s studies have shown a relationship between lanthanide radii and polymorph
  type for the Ln2TiO5 system. By using multiple lanthanides the average la
 nthanide radius can be controlled and so the structure. In this study four
  different combinations of lanthanide titanates were fabricated with the a
 im of producing single phase\, novel design materials with cubic symmetry.
  Whilst it is possible to fabricate homogeneous materials with the general
  Ln2TiO5 stoichiometry using multiple lanthanides there appears to be limi
 ted solubility. The ratio of the lanthanides influences the final structur
 e type and also the solubility. The structure type influences the heavy io
 n irradiation response of these compounds and we report on TEM in-situ exp
 erimental results related to this.\n\nhttps://events01.synchrotron.org.au/
