ceramic

· SbIr

SbIr is an intermetallic ceramic compound combining antimony and iridium, belonging to the family of high-density refractory intermetallics. This material exhibits strong elastic properties and high density, making it of primary interest in research contexts for applications requiring thermal stability and chemical inertness at elevated temperatures. Industrial adoption remains limited, with development focused on specialized aerospace, catalytic, and high-temperature structural applications where traditional superalloys reach their performance limits.
