| Summary: | Synthesis of Cu-Al2O3 nanocomposite powder through a thermochemical method
from the water solution of copper nitrate (Cu (NO3)2.3H2O) and aluminum
nitrate (Al (NO3)6.9H2O) is studied in this research. X-ray diffraction (XRD)
technique, scanning electron microscopy (SEM) and transmission electron
microscopy (TEM) were utilized to characterize the synthesized powder. XRD
results show that γ-Al2O3 phase begins to form at the temperature ≈800°C
during the heat treatment process. Studying SEM micrographs proves that the
nano sized Al2O3 particles are homogenously dispersed in the copper matrix.
XRD results also show that disappearing the reflects of CuO peaks after
performing a reduction chemical reaction at the temperatures above 800°C in
hydrogen atmosphere indicates that such chemical reaction at the temperatures
above 800°C is required in order to achieve Cu-Al2O3 nanocomposite powder. |
