Abstract:

The processes involved in the solution combustion synthesis of alpha-Al2O3 using urea as an organic fuel were investigated. The data describing the influence of the relative urea content on the characteristic features of the combustion process, the crystalline structure and the morphology of the aluminium oxide are presented herein. Our data demonstrate that the combustion of stable aluminium nitrate and urea complexes leads to the formation of alpha-alumina at temperatures of approximately 600-800 degrees C. Our results, obtained using differential thermal analysis and IR spectroscopy methods, reveal that the low-temperature formation of alpha-alumina is associated with the thermal decomposition of an alpha-AlO(OH) intermediate, which was crystallised in the crystal structure of the diaspore.
