- 論文の詳細を見る
Needle-like NaNbO3 has been prepared in two steps by a molten NaOH method. First, Na7(H3O)Nb6O19·14H2O precursor was synthesized by the reaction of Nb2O5 with a molten NaOH at 450°C for 50 h in air. The Na7(H3O)Nb6O19·14H2O precursor was a needle-like single crystal 0.25–1.5 µm wide and >3 µm long. Then, the Na7(H3O)Nb6O19·14H2O precursor crystal transformed to NaNbO3 through an intermediate Na7(H3O)Nb6O19 by a heating above 500°C. The NaNbO3 was a needle-like polycrystal with a perovskite-type structure.
