Preparation and characterization of nanomaterial of LaAl_(11)O_(188) produced by chemical co-precipitation method

摘要

In this paper the methods of chemical co-precipitation method were used to produce nanomaterial of LaAl_(11)O_(18). In order to find the effects of the preparation parameters on its micoscopic structure and the influences of calcinated temperature, keeping warm time and pH value on organizational structure and generate efficiency. And use the X-ray powder diffraction (XRD) and the scanning electron microscopy (SEM) to find the impacts of calcinated temperature, keeping warm time and pH value on the composition and micoscopic structure.
