· Nb5Ge3

Nb5Ge3 is an intermetallic compound from the niobium-germanium system, belonging to a class of refractory metal compounds studied for high-temperature structural applications. This material is primarily of research interest rather than established commercial use; it represents the broader family of refractory intermetallics being investigated as potential alternatives to nickel-based superalloys for extreme-temperature environments where conventional metals lose strength.
