Abstract
The DSC spectra and Gibbs free energy of non-crystalline nano Si3N4 particles were investigated in the temperature range of -100÷500 °C. All analyzes were comparatively performed before and after neutron irradiation. Simultaneously, all thermophysical parameters were considered separately in both heating and cooling processes. The heat flow in Si3N4 nanoparticles was investigated as a function of temperature. The influence of the neutron flux on the Gibbs free energy was comparatively investigated at low temperatures. The effect of neutron transmutations and supercooling on heat transport processes in Si3N4 nanoparticles has been studied.
