· JVASP-109561· MgBe3

MgBe₃ is an intermetallic ceramic compound combining magnesium and beryllium, belonging to the family of lightweight ceramic composites with potential high stiffness-to-weight performance. This material exists primarily in research and development contexts rather than established commercial production, where it is being investigated for applications requiring exceptionally low density combined with rigidity. Compared to traditional ceramics or aluminum-beryllium composites, MgBe₃ represents an alternative approach to achieving lightweight structural performance, though beryllium's toxicity during processing and cost remain significant barriers to widespread adoption.
