Abstract:
composition of MgO and nano boehmite. The reactant and potassium chloride, as the reaction media, were fired at
800-1000 °C at different dwell times (0.5-5 h) in the ambient atmosphere. After washing and filtration, the spinel nano
powder was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Brunauer-Emmett-
Teller (BET) techniques. It was demonstrated that the formation temperature decreased to 850
particles revealed an average size of 30 nm with a narrow size distribution. The mechanism of MgAl
was found to be a template type where the morphology and size of product were similar to those of alumina formed
from boehmite decomposition. Prolonging the reaction time from 0.5 to 3 h, the reaction was further completed and
crystallinity was improved. However, the increase of temperature was more effective in this regard.
MgAl2O4 (MA) nano powder was synthesized via molten salt technique, by heating stochiometric°C. The nano spinel2O4 formation| Rights and permissions | |
