HfTc
HfTc is a thermodynamically stable, metallic binary compound formed from hafnium and technetium.
About HfTc
HfTc is a binary metallic compound composed of hafnium and technetium. As a material that sits directly on the convex hull, it exhibits notable thermodynamic stability, making it a significant subject for structural analysis within its chemical system.
Its metallic nature suggests high electrical conductivity, which is a hallmark of this class of transition metal intermetallics. With extensive structural data available across multiple databases, it remains a well-documented candidate for researchers investigating the interplay between refractory metals and radioactive elements.
Key Properties
Cross-validated computational properties for HfTc, aggregated across 4 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
