Synthesis of MgO nanoparticle via flame metal combustion

Abstracts
Magnesium oxide nanoparticles were synthesized by flame metal combustion method using magnesium powder
as precursor under various conditions. Properties of synthesized MgO nanoparticles were investigated by XRD and
TEM. XRD analyses revealed that MgO nanoparticles synthesized under diverse conditions have high crystallinity
without contamination by precursor magnesium. TEM analyses demonstrated that size distributions can be
controlled by varying experimental conditions. Temperature, concentration and residence time in flame, which can
be adjusted by gas flow rate and feeding rate, affect size distributions of MgO nanoparticles, and in particular,
residence time in flame is the most effective factor.
