Research Abstract	本研究では高速イオン移動が可能な固体材料の創製を目指して新規化合物を合成し、また合成した固体のイオン移動速度を測定してそのイオン移動メカニズムを解明する。また、固体イオニクス材料の実用のための機械的、熱的特性の革新を目指し、新しい液相、気相からの新規合成法を開発することを目的とた。得られた結果は以下の通りである。 1.新規イオニクス固体の合成 (1)(CaF_2)_<1-X>(CaH_2)_Xの系で0<x<0.5の範囲で固溶体が形成することを明らかにし、また電気化学測定の結果この材料がハイドライドイオン伝導性であることを示した。 (2)PbWO_4を母体とする灰重型酸化物を合成し、これらが酸化物イオンあるいはリチウムイオン伝導体であることを示した。 (3)化学安定性の高い安定化ジルコニアマトリックス中にセリアを分散させた新しいイオン伝導性固体材料を開発した。 (4)架橋構造を有する樹脂状のポリマー電解質を作製し、これまでにない高いイオン伝導性を有することを示した。 2.新規プロセッシング法の開発 (1)フッ化物錯体を出発物質として液相での平衡反応を用いる新しいイオン伝導性薄膜形成法を開発し、ZrO_2やペロブスカイト型酸化物薄膜を得た。 (2)プラズマを導電性気体として用いる気相電気化学析出法を構築し、これを用いて配向した銀イオン導電性AgI薄膜を形成できた。 (3)ジルコニアマトリックス中にアルミナ微粒子を分散させることでイオン伝導性を損なうことなく機械的強度を向上させる方法を見いだした。
