用醇-水乳浊液法制备了立方系尖晶石结构纳米ZnAl2O4,用XRD和SEM对其进行了表征。结果表明,该ZnAl2O4纳米颗粒粒径在30~50nm之间,分散均匀,大部分粒子都已独立成核,粒径随热处理温度的升高而变大。
Cubic spinel nanostructured ZnAl2O4 was prepared by alcohol-water emulsion method and characterized by XRD and SEM. The results show that the particle size of the ZnAl2O4 nanoparticles is 30 ~ 50nm, and they are uniformly dispersed. Most of the particles have been nucleated independently. The particle size increases with the increase of the heat treatment temperature.
