Abstract
The colloidal solutions of the Ag-Cu nanoparticles (NPs, 10-32 nm) were prepared by solvothermal reactions. The samples of dried AgCu NPs and the resulting microstructures after heat treatment in air were investigated by various methods including electron microscopy (TEM, SEM) and high-temperature X-ray powder diffraction (HTXRD). The AgCu randomly mixed, Cu-rich, and Ag-rich face centred cubic crystal lattices were detected during the experiments. The temperature induced sintering was observed experimentally by HTXRD at 250 degrees C. The phase transformations at high temperatures were monitored by differential scanning calorimetry. The formation of the Ag-rich grains during heating in air and evolution of copper oxide microstructure were detected.
Abstract (in Czech)
Koloidní roztoky nanočástic AgCu NPS (10-32 nm) byly připraveny solvotermální reakcemi. Vzorky sušené AgCu NP a výsledné mikrostruktury po tepelném zpracování na vzduchu byly zkoumány různými způsoby, včetně elektronové mikroskopie (TEM, SEM) a vysoké teploty X-ray práškové difrakce (XRD). AgCu náhodně smíchány, Cu-bohaté, a v průběhu experimentů bylo zjištěno Ag bohaté plošně centrovanou kubickou krystalovou mříže. Indukovaná slinovací teplota byla pozorována experimentálně HTXRD při 250? C. Fázové přeměny při vysokých teplotách byly sledovány pomocí diferenční skenovací kalorimetrií. bylo zjištěno tvorba Ag-bohaté zrna při zahřívání na vzduchu a vývoji oxidu mědi mikrostruktury.
