## Description

- description: 本研究では高圧拡散制御（HPDC）法という新しい合成技術を開発した。これは立方アンビル装置による高圧合成と異方性拡散制御を組み合わせたものである。4GPa、1000℃以上の高圧・高温環境下で温度・圧力・電圧を同時制御し、非平衡状態を利用して準安定材料を作製できる。この手法をNaAlB14多結晶体に適用したところ、Naイオンを選択的に抽出し、基本構造を保ったまま準安定なAlB14を合成することに成功した。高圧による体積変化を利用して粒界接触を維持しつつNaを抽出でき、電気抵抗も大きく低減した。この手法は、構成元素間の結合強度差を持つ様々な化合物に応用可能である。
