· Be2 Ta4

Be₂Ta₄ is an intermetallic compound combining beryllium and tantalum, belonging to the family of refractory metal intermetallics. This material is primarily of research and development interest rather than established production use, as compounds in the Be-Ta system are investigated for potential applications requiring extreme temperature stability and low density combined with high melting points.
