comparative study of two surfactant from polyoxyethylene sorbitan monolaurate family for preparation of tho2 nanoparticles

In this research, polyoxyethylene sorbitan monooleate-80 (psm-80) and polyoxyethylene sorbitan monooleate-20 (psm-20) surfactants were used for preparation of tho2 fuel powders# (psm-20) and (psm-80) surfactants were applied to provide suitable porosity in nuclear fuel texture# the surface tension, and interfacial tension were investigated for psm-80 and psm-20 surfactants# the slow micellization of psm-80 would be the reason for the higher surface tension and interfacial tension values of psm-80# tho2 particles were characterized by means of differential scanning calorimetry (dsc) and scanning electron microscopy (sem) analyses# results show that tho2 particles prepared using psm-80 has larger granulation#
