Thermal degradation of aluminum formate sol-gel; synthesis of α-alumina and characterization by 1H, 13C and 27Al MAS NMR and XRD spectroscopy
Thermal transformation of aluminum formate sol-gel to α-Al2O3 is reported. XRD and IR spectroscopy confirmed the presence of the precursor at 25 °C, and showed the precursor hydroxide at 200 °C. After calcinations, amorphous Al2O3 and η-Al2O3 were present at 400 °C and 800 °C, respectively. Coordina...
