ABSTRACT

In this study, the crystal characteristics of commercial AlN powders with sizes of “μm” and “nm” were selected through XRD analysis and then sintered at different temperatures through an induction heating furnace to investigate the optimized sintering temperature and physical properties. The sintering temperature was 1,500, 1,700, and 1,900°C in the N₂ atmosphere, and the optimized sintering temperature conditions were established for the sintered AlN pellets using SEM, XRD, and Raman analysis. Additionally, impedance analysis was performed to confirm the electrical properties of the optimized AlN pellet without sintering additives.
