· JVASP-35108· Al3BN4

Al3BN4 is an advanced ceramic composite material combining aluminum with boron and nitrogen phases, positioned in the family of boron nitride-reinforced ceramics. This material is primarily investigated in research and development contexts for applications requiring simultaneous high stiffness and moderate density, with potential advantages in thermal management and wear resistance compared to monolithic ceramics or conventional aluminum alloys. Industrial adoption remains limited, but the material is of interest to engineers working on next-generation structural ceramics, particularly where weight reduction and thermal stability are design priorities.
