Carbothermal Synthesis of Aluminum Nitride Using Sucrose

Several aluminum oxides (α‐Al 2 O 3 , θ‐Al 2 O 3 , and AIOOH) were examined to study the differences in reaction behavior and powder characteristics during carbothermal nitrida‐tion to AIN using sucrose and carbon black. The reaction conditions investigated were carbon‐to‐alumina ratio, reaction temperature, and time. Carburized sucrose resulted in Full conversion to AIN and produced a uniform powder morphology using a near‐istoichiometric …
