| 英文摘要 | A modified carbothermal reduction-nitridation (CRN) method was proposed to synthesize fine AN particles using gamma-Al2O3 and sucrose as raw materials which were pre-treated as cellular foams. The reaction procedure and the produced AlN were investigated by XRD, SEM and TEM. XRD result suggests that gamma-Al2O3 transferred into AlN without transformation into alpha-Al2O3. HRTEM shows that gamma-Al2O3 particles are covered by amorphous carbon from sucrose inhibiting the transformation of alpha-Al2O3 from gamma-Al2O3 in the synthesis procedure. The foamed structure is of benefit to the diffusion of N-2 and the produced CO. The minimum reaction temperature is 1450 degrees C for full conversion of Al2O3 to AlN. SEM photographs show the particle size of synthesized AlN is 50 nm. This study demonstrated an efficient way to synthesize fine AlN powders which are urgently required for the manufacture of advanced AlN ceramics. |
