Abstract:	中文摘要本研究主要目的係利用四氯化鈦酸解所得之奈米級二氧化鈦合成超微細鈦酸鋇。酸解所得之二氧化鈦粉體為針片狀且約在80-90奈米，再利自製所得之二氧化鈦粉體作為鈦源，使用氫氧化鋇為鋇源，以水熱合成的方法，合成條件在中低溫（ ABSTRACT The objectives of this research were to synthesize ultra-fine BaTiO3 with home-made nano-size TiO2 using the hydrothermal method and investigate the influence of synthesis parameter. The nanosized TiO2 sol was successfully synthesized by the direct thermal-hydrolysis of titanium tetrachloride with various acids. According reports, barium titanate is an important electronic ceramic and employed in the powder form as the fundamental dielectricmaterial of multilayer capacitors. Due to the closed nature of the hydrothermal system and the desire for particles of decreased size, experimental designs were employed to investigate the effects of various synthesis process treatment on the final particle attributes using low reaction temperatures (
