Ceramic matrix containing zirconolite, hollandite, and perovskite phases is proposed as a
potential host for HLW immobilization. Hollandite phase principally immobilizes Cs, while …

This review provides a broad overview of the structural characteristics, compositional
flexibility, and structure–property relationships of hollandite materials. Hollandites have a …

The impact of composition on the tunnel features of hollandite materials for the purpose of
radioactive cesium (Cs) immobilization was evaluated. The barium (Ba) to cesium (Cs) ratio …

Hollandite ceramics are well-recognized as a promising host for immobilizing radioactive
cesium. In the present paper, the [Ba x Cs y][(Al 3+, Ti 3+) 2 x+ y Ti 4+ 8-2 xy] O 16 (0.4≤ x …

This study explores the corrosion interactions between stainless steel 316 (SS316), a
candidate nuclear waste canister material, and Cr-containing hollandite (Ba 1.15 Cr 2.3 Ti …

In this paper, we present a productive low-temperature fabrication of Cs-hollandite ceramics
by adding Bi 2 O 3 as a sintering aid to achieve high cesium retention. The effects of Bi 2 O 3 …

Hollandite solid solutions along the A‐site compositional range from the pure barium end‐
member Ba1. 33Ga2. 66Ti5. 34O16 to the pure cesium end‐member Cs1. 33Ga1. 33Ti6 …

The titanate-based hollandite structure is proposed as an effective ceramic waste form for Cs-
immobilization. In this study, quantum-mechanical calculations were used to quantify the …

Cs2TiNb6O18 is a potential ceramic wasteform for the long-term immobilization of
radioactive cesium. Cs2TiNb6O18 was synthesized using the aqueous precursor method …

The radiation damage tolerance of nuclear waste forms is dependent on the material's
resistance to defect formation and its ability to accommodate structural distortions that arise …
