A modified microwave-assisted polyol method was applied to prepare nanoparticulate ceramic powders of different oxides, i.e. Gdsub 2}Osub 3}, AlO(OH) (boehmite) and TiOsub 2}. Due to the good dielectric properties of the utilised solvents, such as ethylene glycol, diethylene glycol and 1,4 butanediol, a significant decrease in reaction time was achieved under microwave heating. In the case of AlO(OH)
应用改进的微波辅助多元醇方法制备不同氧化物的纳米颗粒陶瓷粉末,即 Gdsub 2}Osub 3}、AlO(OH)(勃姆石)和 TiOsub 2}。由于所用溶剂(如乙二醇、二甘醇和 1,4 丁二醇)的良好介电性能,微波加热下反应时间显着缩短。在 AlO(OH) 和 Gdsub 2}Osub 3} 的情况下,获得 <5 nm 的初级粒径。发现勃姆石嵌入溶剂中。显示了该方法的一般适用性,并描述了在性能和可加工性方面的优势。使用X-射线衍射法、电子显微术和物理吸附来研究由此制备的粉末。
