CaTiO3∶Zn纳米粉体的溶胶凝胶法制备及性能研究OA北大核心CSCDCSTPCD
Preparation and properties of CaTiO3 ∶ Zn nanoparticles based on sol-gel method
采用溶胶凝胶法制备了CaTiO3∶Zn纳米粉体,研究了所制粉体的微观结构及性能.结果表明,所制粉体粒径约50 nm,主晶相为CaTiO3,Zn以Zn2TiO4形式存在于晶相中.1 150℃下烧结所得CaTiO3∶Zn纳米粉体性能较优:比固相法的烧结温度降低约250℃,相对介电常数εr=155,品质因数Q·f提高至6 633 GHz.
Nano-sized CaTiO3:Zn particles were successfully synthesized through sol-gel technique. The microstructure and other properties of the prepared nano particles were investigated. The average particle size of the CaTiO3: Zn powders calculated from TEM micrograph is about 50 nm. CaTiO3 is formed as the 'major phase, and the added Zn exists as Zn2TiO4 phase. The CaTiO3:Zn ceramics can be well sintered at 1 150 ℃, about 250 ℃ lower than those of ceramics ob…查看全部>>
