Synthesizing of nano-sized AlN powder with alumina balls

다국어 초록 (Multilingual Abstract)

In this study, a new method called the dynamic carbothermal reduction and nitridation (DCRN) method was used for nanosized aluminium nitride (AlN) powder production. The carbothermal reduction process was carried out in an atmospherecontrolled modified rotary-type tube furnace in the new method and reactants are rolled with Al2O3 balls continuously duringthe process. This is a novel approach in synthesizing AlN powders. This study shows that high quality uniax homogeneousparticles of nano sized aluminium nitride (AlN) powder could be produced using this method (DCRN) from aluminiumhydroxide (Al(OH)3) starting powders as low as 1450 oC. Produced powders were characterized by X-ray diffractometer(XRD) and field emission scanning electron microscopy (FESEM) analyses. As the result, nano-sized AlN powders weresynthesized at 1450 oC for 1.5 hrs under by dynamic carbothermal reduction and nitridation (DCRN) method used Al2O3 balls.
