dc.description.abstractThe anisotropic thermal expansion and crystal structure of K2NiF4-type CaErAlO4 have been investigated by neutron diffraction from 298 to 1473 K. The average thermal expansion coefficient (TEC) along the c axis αc is larger than that along the a axis, mainly due to the larger Al–(apical oxygen O2) TEC compared to the Al–(equatorial O1) TEC. The larger Al–O2 TEC is attributable to the weaker Al–O2 bond. Contrary to the literature, the mean TEC of K2NiF4-type CaErAlO4 is larger than that of perovskite-type ErAlO3.en_AU
