· JVASP-35150· GaB3N4

GaB₃N₄ is an advanced ceramic compound combining gallium, boron, and nitrogen—a material class known for exceptional hardness and thermal stability. While primarily a research-phase compound, it belongs to the family of boron nitride and gallium nitride ceramics that show promise for extreme-environment applications where conventional ceramics face limitations. The gallium-boron-nitrogen system is being explored for ultra-high-temperature structural applications, semiconductor processing, and wear-resistant coatings where the combination of covalent bonding and wide bandgap properties could outperform established alternatives.
