| Summary: | 碩士 === 南台科技大學 === 電子工程系 === 97 === 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).
