Abstract
The hexagonal rare earth aluminates REAl11O18, REMgAl11O19, and RELi0.5Al11.5O19 were prepared by solid state reaction. The phases REA111O18 were found to exist only for RE = La, Ce, REMgAl11O19 for RE = La – Gd, and RELi0.5Al11.5O19 for RE = La – Eu. The values of c/a indicate REMgAl11O19 and RELi0.5Al11.5O19 to belong to the magnetoplumbite type. This may also be true for REA111O18 which was formerly assumed as a β-alumina phase.
