“…However, the purity of the powder they produced was only 950/0.Zyatkevich et al 15 also adopted a low temperature plasma reactor to produce AIN powder .. Vissokov and Brakalov 16 used aluminium powder as a feed material instead of bulk aluminium electrodes in an arc plasma reactor to produce ultrafine AIN powder and reported that the rate determining step of the process is the evaporation of aluminium.…”

It has beenfound that the reaction rate between alumina and carbon in nitrogen can be considerably increased by using AI(OH)3-C mixtures instead ofll. in the starting mixtures should be greater than the stoichiometric ratio to complete the reaction. It was observed that alumina is reduced and nitrided to form aluminium nitride via spinel type aluminium oxynitride which is an intermediate compound. The overall reaction rate increased with decreasing AI(OH)3particle size and increasing nitrogenjlowrate.It is thought that thefaster reaction rates obtainedfrom AI(OH)3-C mixtures were derivedfrom the high specific surface area of transition aluminas, such as y A1 2 0 3 , whichformed during heating of the samples to the reaction temperature. The particle morphologies of the Al (0 H) 3 powders did not change during the reduction and nitridation reaction, an important attribute to the process.MSTj1346c
