In this work, differential scanning calorimetric (DSC) analyses were performed in an Ar inert medium the temperature range of 100–750 K for Y 2 O 3 compound with purity rate 99.99%, density powder form is 0.069 g/cm , specific surface area 100–150 m /g, particle size 8–10 nm irradiated fast neutrons different intensities ([Formula: see text] MeV). Using mathematical approximation methods, equations dependence heat flux function on and capacity after irradiation at over a wide determined. It was found that [Formula: K, value increases by 16.6%, up to 86 mW case maximum radiation. At all radiation intensities, anomalies recorded very small changes observed spectra related internal structural transitions.
