This research investigates the synergistic effects of hexagonal boron nitride (h-BN) as sintering additives in aluminum nitride (AlN) ceramic processing. The study aims to assess the impact of incorporating h-BN on the sintering behavior and properties of AlN ceramics. h-BN, renowned for its thermal stability and lubricating properties, is explored as a strategic additive to enhance the densification process and overall performance of AlN-based materials. The research focuses on understanding the influence of varying concentrations of h-BN on sintering temperatures, densification kinetics, and mechanical properties of the AlN ceramics. Additionally, the investigation into the coefficient of friction (CoF) of samples with varying concentrations of h-BN revealed distinct trends as the disc surface temperature increased during continuous braking tests. This investigation provides valuable insights into the role of hexagonal boron nitride as a sintering aid tailored for AlN, contributing to the optimization of processing parameters and the advancement of high-performance ceramic materials.
