ErAl9(Fe2Si3)2
metal· ErAl9(Fe2Si3)2
ErAl9(Fe2Si3)2 is an intermetallic compound in the erbium-aluminum-iron-silicon system, representing a complex ternary or quaternary metallic phase with ordered crystal structure. This material belongs to the family of rare-earth-containing intermetallics and is primarily of research and development interest rather than established commercial production. The compound's potential lies in high-temperature applications where rare-earth strengthening and intermetallic hardness could provide advantages, though engineering adoption remains limited pending further characterization and cost-benefit validation against conventional superalloys and composite materials.
