Optimized preparation of c-axis-aligned polycrystal of doped lanthanum silicate oxyapatite and evaluation of its electrical properties

Koichiro Fukuda Shu Okada Iori Terao Atsushi Mineshige Daisuke Urushihara Toru Asaka

Journal of the Ceramic Society of Japan 131(11) 870-876 2023年11月

The two types of c-axis-aligned polycrystals of lanthanum silicate oxyapatite (LSO) doped with K2O and Al2O3 were prepared by the templated grain growth method with different template/matrix mass ratios of 11.1/88.9 and 5.9/94.1. The template part...

Preparation of grain-aligned polycrystal of doped lanthanum silicate oxyapatite by templated grain growth method and evaluation of its structural and electrical properties

The disk-shaped sintered compacts consisting mainly of c-axis-aligned lanthanum silicate oxyapatite (LSO) polycrystals doped with K2O and Al2O3 were prepared by templated grain growth method. The tabular single crystals of K2O- and F-doped LSO wer...

Formation of La-rich tysonite nano-precipitates in fluorite Ba<inf>0.6</inf>La<inf>0.4</inf>F<inf>2.4</inf>

Shun Sasano Ryo Ishikawa Kazuaki Kawahara Atsushi Mineshige Naoya Shibata Yuichi Ikuhara

Journal of Power Sources 557 2023年2月

Ba0.6La0.4F2.4 (BLF) is one of the promising candidates for solid-state electrolytes in fluoride-ion batteries owing to the wide electrochemical potential window. Compared with a BLF single crystal, the microstructure-modified BLF polycrystals by ...

Ionic Conduction in Sr-Doped CeF<inf>3</inf>as Studied by ¹⁹F NMR and AC Impedance Measurement

Miwa Murakami Seiya Matsumoto Atsushi Mineshige

Journal of Physical Chemistry C 126(47) 20135-20142 2022年12月

Among the three inequivalent fluorides in tysonite CeF3(F1, F2, and F3 in the ratio of 12:4:2 per unit cell), we show by 19F solid-state NMR that F1 is solely responsible for the ion conductivity in Ce1-xSrxF3-x(x = 0.001) at 0 °C. It is further s...

¹⁹F NMR studies on ionic conduction pathways in tysonite-CeF<inf>3</inf>

Miwa Murakami Atsushi Mineshige

Journal of Physics and Chemistry of Solids 161 2022年2月

There has been a long-standing controversy over ion conducting pathways in tysonite. To unravel the pathways in CeF3, high-resolution MAS NMR spectra of 19F in CeF3 at −40–240 °C are analyzed on the bases of the calculated dipolar coupling tensor ...
