ABSTRACT |
Barium Titanate(BaTiO$_3$) nanoparticles were prepared at 22$0^{circ}C$ through glycothermal process by using barium hydroxide and amorphous titanium hydrous gel as precursor and 1,4-butanediol and distilled water as solvent. It is demonstrated that the size of BaTiO$_3$ particles can be controlled by reaction conditions such as various content of 1,4-butanediol/distilled water volume ratio. This processing method can fabricate BaTiO$_3$ powders, which have a narrow distribution and exhibit good dispersion. The particle size of BaTiO$_3$ powders obtained by glycothermal process were about 50 nm to 200 nm on the condition that reaction temperature was 22$0^{circ}C$ and holding time was 24 h. ヨ⨀ |
