| Abstract: | AlN powder has been prepared by carbon thermal red uc tion method. Effects of starting raw materials, reaction temperatures and variou s additives on synthesised AlN powder have been discussed. The powder prepared h as been examined using XRD, SEM and chemical analysis. The results show that act ivated carbon and Al(OH) 3 are conducive to nitridation reaction rate and incre ase nitrogen content. CaF 2 can be used as a good catalyst for this reaction ,while powder of AlN can effectively increase nitridation rate. |
