· SbRu

SbRu is an intermetallic ceramic compound combining antimony and ruthenium, belonging to the class of refractory intermetallics. This material is of primary interest in high-temperature and harsh-environment applications where conventional ceramics or metals reach their performance limits. SbRu exhibits notable stiffness and density characteristics that position it for specialized aerospace, catalytic, or materials research contexts where thermal stability and chemical resistance are critical.
