Fe1Li1Pt2
Fe1Li1Pt2 is a metastable, semiconducting ternary alloy composed of iron, lithium, and platinum that is studied for its unique electronic properties.
About Fe1Li1Pt2
Fe1Li1Pt2 is a complex ternary intermetallic compound classified within the platinum-group alloy catalysts. Its electronic character is defined as semiconducting, which distinguishes it from the typically metallic behavior found in many related platinum-based systems. The material exhibits significant structural diversity, with numerous reported configurations across crystallographic databases. Due to its position above the thermodynamic hull, Fe1Li1Pt2 is considered a metastable phase. This characteristic suggests that while it may be difficult to synthesize or maintain under standard conditions, it remains a subject of interest for researchers investigating the limits of phase stability in ternary metal systems.
Key Properties
