Hydrothermal synthesis of perovskite-type BiFeO_3

概要
- 論文の詳細を見る
Single crystals of BiFeO_3 were prepared by hydrothermal synthesis using hydrate sodium bismuth oxide (NaBiO_3・nH_2O) and iron nitrates (Fe(NO_3)_3・9H_2O) in the potassium hydroxide solutions. The size of BiFeO_3 single crystals increased with the reaction temperature and duration. Single crystals of sillenite-type Bi_<12.5>Fe_<0.5>O_<19.5> and Bi_2Fe_4O_9 were also obtained depending on the conditions. From the chemical analysis, the chemical composition of the crystals was deduced to be Bi_<0.96>K_<0.03>FeO_3. Although the crystals contained a small amount of potassium, the lattice parameters of the crystals agreed well with the pure BiFeO_3 and the Curie temperature was not affected by this replacement.
