· JVASP-107041· NbB4Mo3

NbB4Mo3 is a refractory metal boride compound combining niobium, molybdenum, and boron—a research-phase material belonging to the ultra-high-temperature ceramic and hard material family. This compound is investigated primarily for extreme-environment applications where conventional superalloys and ceramics reach their limits, with potential relevance in aerospace propulsion, cutting tools, and electronic device protection; however, it remains largely experimental with limited commercial deployment, making it most suitable for specialized high-performance projects where development costs are justified.
