| Abstract: | Excessive interfacial diffusion during low-temperature co-firing of Al 2 O 3 /NCZF composites degrades electromagnetic properties by introducing unwanted ions into ferrite or dielectric ceramic sites. To suppress interdiffusion, sol-gel-derived SiO 2 /ZrO 2 barrier layers were fabricated at the interface. The microstructure and elemental distribution across the Al 2 O 3 /NCZF interface were characterized using SEM, EDS, and EPMA. XRD, HRTEM, and AC-TEM characterized phase composition, microstructure, and dislocations. Results indicate that after the introduction of the SiO 2 and ZrO 2 barrier layers, the phase structures of both materials remained unchanged, and no new phases were formed. Under the combined effect of ZrO 2 capturing high-valent ions via oxygen vacancies and SiO 2 effectively capturing transition metal ions and Zn2+-enriched segregation zone, the ZrO 2 layer demonstrates superior blocking against Al3+, Zn2+, and Ni2+ diffusion. In contrast, SiO 2 is more effective against Fe3+ and Cu2+. Both achieve optimal inhibition at 2–3 layers and help alleviate interphase lattice distortion. Consequently, the dielectric loss decreased from 0.0018 to 0.0015 (SiO 2) and 0.0014 (ZrO 2), while the saturation magnetization increased from 48.613 emu/g to 59.861 emu/g (SiO 2) and 59.668 emu/g (ZrO 2). Notably, the achievement of excellent electromagnetic properties through the introduction of these diffusion barrier layers does not compromise thermal management efficiency. [ABSTRACT FROM AUTHOR] |
