MgO nanoparticles were prepared by using a direct deposition method
in which
the precursor
alkaline magnesium carbonate/paraffin
was firstly obtained by direct precipitation of the mixture of MgCl2·6H2O and Na2CO3 in paraffin emulsion
and then calcined at 600℃. The nanoparticles were characterized by using TG-DTA
FTIR
XRD
BET and FESEM. Under the optimum conditions
the as-prepared MgO nanoparticles were hexagonal crystals with a uniform size of around 60 nm and a specific surface area of 132.54 m2·g-1. The optimum preparation conditions were: MgCl2·6H2O concentration
