Low temperature DSC investigation of neutron irradiated non-crystalline Si3N4 nanoparticles

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.

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
