HfRu is a ceramic intermetallic compound combining hafnium and ruthenium, belonging to the refractory metal ceramic family. This material is primarily of research and development interest for ultra-high-temperature structural applications where exceptional thermal stability and mechanical rigidity are required, particularly in aerospace and nuclear contexts where conventional superalloys reach their limits.
