Effect of Solvents on the Synthesis of SrAl2O4 Nanoparticles by Reverse Micelle Process

Three types of solvents with different polarity (cyclohexane, toluene and benzene), a nonionicsurfactant span 40 were used to prepare strontium aluminate (sral2o4) spinel nanoparticles by areverse micelle method. the structure of sral2o4 nanoparticles was characterized by x-raydiffraction (xrd). the morphology and size of the synthesized materials were studied using fieldemission scanning electron microscope (fesem) and transmission electron microscope (tem)with using software of image j. the effect of polarity of solvent on the size and morphology ofnanomaterials was studied. it was found that increasing the polarity of solvent affected the averagecrystallite size of the final product and led to the formation of larger particles. furthermore, theaverage particles size was increased from 22 to 37 nm. x-ray diffraction analysis of all the powderswas calcined at 1000°c for 2hrevealedthe formation single phase hexagonal spinel structure.polarity of solvent is a major factor in controlling the final particles size of sral2o4 powder.
