Mo1Nb1Ta2
Mo1Nb1Ta2 is a semimetallic intermetallic compound formed from molybdenum, niobium, and tantalum that exists in a metastable state.
About Mo1Nb1Ta2
Mo1Nb1Ta2 is a complex intermetallic compound composed of molybdenum, niobium, and tantalum. As a near-zero-gap material, it exhibits semimetallic electronic behavior, positioning it as an interesting subject for studies into the fundamental physics of multi-element refractory alloys.
Despite its structural diversity, with numerous reported configurations, the compound is identified as being above the thermodynamic hull. This suggests that while it can be synthesized, it may face challenges regarding long-term phase stability compared to simpler binary or elemental systems.
Key Properties
