· Zr4 Al3

Zr₄Al₃ is an intermetallic compound combining zirconium and aluminum, belonging to the family of refractory intermetallics that exhibit high melting points and potential structural performance at elevated temperatures. This material is primarily investigated in research contexts for aerospace and high-temperature applications where lightweight, thermally stable phases are needed; it represents an experimental composition rather than an established commercial alloy, with potential relevance to advanced jet engine components and thermal barrier systems where zirconium-aluminum systems show promise for combining low density with thermal stability.
