Sažetak
Microstructural properties of six samples, prepared by rapid hydrolysis of aluminum secbutoxide,
were investigated at RT using field emission scanning electron microscopy (FE SEM), X-ray
powder diffraction (XRD) and Fourier transform infrared (FT-IR) spectrometry. The results of structural
analysis show that, regardless of a significant difference in the processing parameters (pH, temperature,
time of synthesis), all products contain boehmite as the only crystal phase present. The results of FE-SEM
analysis indicate a significant difference in the morphology of obtained boehmites (plates, needles, granules).
The results of line-broadening analysis of powder diffraction patterns (Le Bail method – program
GSAS) indicate the presence of very small anisotropic crystal domains (around 1.5 to 7 nm in the direction
010; around 3 to 16 nm in the direction perpendicular to 010). In all cases the parameters that contribute
to the strain broadening of diffraction lines decrease to nearly zero, which suggests that the obtained
boehmites are almost strain-free. (doi: 10.5562/cca1884)
