Influence of Fe@MnAl2O4 and synthesis of novel compound Mn0.83Fe0.21Al1.96O4
چکیده انگلیسی

This communication demonstrates iron substitution in galaxite and the synthesis of a novel composite, Mn0.83Fe0.21Al1.96O4, by a simple thermal method. Hence, metal powders were heated at 1100 °C temperature for 72 h. When cooled down gradually to room temperature, the sample delaminated. Interestingly, on the sample surface, microwires were formed as timber shape with a rectangular cross-section (length>150 μm and diameter of 5–20 μm). Moreover, nanowires (77–97 nm) were observed and the surface of the sample was greenish. However, nanowires (38–53 nm) were observed on the substrate. The crystallinity and average size of the structure were formed increased by substitutions of iron ions. We discovered that the influence of temperature is very important in the wire formation process.
