| Abstract: Monodispersed spherical MgO nanocrystallites were successfully prepared by a novel gel-network precipitation process. The face-centred cubic samples were with narrow size distribution of 10～15 nm. The formation process and structure of MgO nanocrystallites were investigated by means of TG-DTA, FTIR, XRD and TEM. The results show that the particle sizes are related to the network structure of gelatin, not only can the shapes and sizes of nanocrystallites be controlled, but the aggregation and agglomeration can be prevented by gel-network. The products have smaller particle size and better homogeneity. |
