Alumina combustion synthesis
Combustion synthesis is a process that uses a highly exothermic redox reaction between fuel and oxidizer to produce metal oxides of desired properties. In this work, combustion synthesis of aluminium oxide from aluminium nitrate as oxidizer and alanine as fuel was investigated. The product was thermally treated at various temperatures and characterized using differential thermal and thermo-gravimetric analysis (DTA-TGA), Fourier transformed infrared spectroscopy (FTIR), scanning electron microscopy (SEM), powder X-ray diffraction (XRD) and laser diffraction particle size analysis. The XRD results show that the initially amorphous product shows peaks for γ-alumina after thermal treatment at 800 °C and peaks for α-alumina after treatment at 1000 °C. The FTIR spectra confirm the existence of Al-O bonds. According to the particle size distribution results, the average particle size of the obtained alumina is around 140 micrometres.
