本論文利用不同的研磨方法,將固態反應法(solid-state reaction) 燒結成的鈦酸鋇(BaTiO3)研磨成微米級粉體以及奈米級粉體,微米級粉體約 5μm以及奈米級粉體約 80nm。並利用兩種粗細不同的鈦酸鋇粉體調配出比例不同之組合。
實驗結果可知原始粉體愈細小其燒結溫度愈低。在同樣燒結條件下,奈米級粉體所形成的鈦酸鋇陶瓷體之燒結溫度較微米級粉體所形成的陶瓷體低150℃。而鈦酸鋇陶瓷的密度以及介電常數則取決於粉體的混合比(微米粉體/奈米粉體)。奈米級粉體經燒結所形成的鈦酸鋇陶瓷在室溫之介電常數約為5500遠大於只有1800微米級粉體所形成的陶瓷體。本研究由實驗結果中得知,最好之結果是由微米級粉體和奈米級粉體(C4/F6)混合組成,其高密度性最高、低孔隙及最高之介電常數。
In the thesis, we used two kind of different size barium titanium (BaTiO3)powders, which is the micro size fine powders (about 5μm) and nano size coarse powders (about 80nm).
For the same sintering conditions, the sintering temperatures of BaTiO3 ceramics, nano size powder is 150℃ lower than micro size powder, but the relative density、dielectric constant of the ceramics was depend on the ratio of (micro powders/nano-powders). The dielectric constant of nano size powder BaTiO3 ceramic (about 5300) is larger than micro size powder BaTiO3 ceramic (about 2300), and the maximum of density、dielectric constant occurs at (coarse powders/fine-powders) equal (C4/F6).
