Abstract ▼ AI-Helper

Sintering of the Cu nanoparticle at low temperatures resulted in exothermic behavior after its initiation. The calorimetry study of the heating of a 20nm copper nanoparticles agglomerate revealed the evolution of 41.17J/g of heat between 170oC and 270oC. High resolution transmission electron microscopy (HRTEM) images indicated that the heat generation was accompanied by sintering. The surface energy of the 20nm copper nanoparticles was estimated to be 1.23x103erg/cm2 based on the heat released during sintering. The in situ high resolution transmission electron microscope (HRTEM) investigation showed that vigorous sintering occurred between 217 and 234oC, which took place through the dislocation sintering mechanism.
