Morphology and structure of nano MgO prepared by a novel nitrogen-protective pressurization method
Abstract
A new micro stereoscopic structure of nano MgO was prepared by a novel nitrogen-protective pressurization method and characterized by SEM, EDS, and XRD. The nano MgO was formed by spherical units, and under the action of adsorption, the spherical units formed nanosheets by connecting to one another. Moreover, the units and sheets further gathered into laminations of nano MgO. The grain sizes of the nanosheet and laminate nano MgO were 11.8 nm and 367.6 nm, respectively, which were prepared by a novel method. The influence of nano MgO on morphology and structure were revealed by changing the amount of PVA, calcination time, and pressure.
