Synthesizing of nano-sized AlN powder with alumina balls

2021    Canikoglu, Nuray

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