FeGa2O4 nanowires preparation after milling and annealing

Nov 15, 2019· In this work, FeGa 2 O 4 nanowires were prepared using high-energy ball milling and subsequent annealing from GaN samples doped with Fe. The structural and chemical characterization were studied by X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calorimetry (DSC-TGA), and transmission electron microscopy (TEM). The XRD patterns showed that …

FeGa2O4nanowires preparation after milling and annealing

Nov 15, 2019· In summary, FeGa 2 O 4nanowireswere obtained in Fe doped GaN powders after high-energyball millingfor 20 h and subsequently annealed at 1100 °C. DSC-TGA analysis demonstrates GaN: Fe decomposition at 1100 °C. TEM investigations show that thenanowiresare quite straight with diameters of about 50–60 nm and lengths up to 2 μm.

Efficient production of ZnOnanowiresby aball milling

ZnO powder was mechanically milled in aball mill. This procedure was found to greatly increase its evaporation ability. The anomalous evaporation behaviour was caused by the disordered structure of the milled material and was not related to the increase in its surface area aftermilling. ZnOnanowireswere synthesized by evaporation of this milled precursor.
