N2 - High-resolution electron microscopic studies have revealed variations in the length of the tunnel cavities within Ba2Ti9O20, from the normal cavity of length three sites to ones of four and five sites. These elongated cavities can be described in terms of an intergrowth of distorted synroc hollandite BaAl2Ti6O16 with Ba2Ti9O20. The implications of such intergrowths in the immobilization of radioactive cesium are discussed, and a potential homologous series of phases is predicted.
