| Tóm tắt: | X-ray diffractometer (XRD)
The detected peaks in the XRD patterns were identified as rhombohedra perovskite structure of BiFeO3 with space group R-3 m and lattice parameters a = b = c = 3.9520 (Å).
Scanning electron microscope (SEM)
The BiFeO3 images, at 100 μm and 20 μm magnifications, exhibit agglomerated particles of various sizes and shapes.
The independent variables and their levels
The low, central, and high levels of the variables are designated as -1, 0, and + 1, respectively. Tests outside the experimental range are denoted as ± α, and they help to predict response functions outside the cubic domain.
