KZrBe2
metal· JVASP-70297· KZrBe2
KZrBe2 is an intermetallic compound combining potassium, zirconium, and beryllium elements, representing an experimental material in the family of lightweight high-strength intermetallics. This ternary system is primarily a research material investigated for potential aerospace and structural applications where the combination of low density with high elastic stiffness could offer weight savings; however, limited industrial adoption and challenges associated with beryllium toxicity and processing difficulty have constrained its practical use compared to conventional titanium alloys and aluminum composites.
