CoW3
CoW3 is a metallic cobalt-tungsten intermetallic compound that exists as a metastable phase.
About CoW3
CoW3 is a metallic intermetallic compound composed of cobalt and tungsten. As a metallic phase, it exhibits characteristic electron delocalization that influences its physical properties and potential interactions within complex alloy systems.
Despite being identified in numerous structural configurations across multiple databases, this compound is categorized as thermodynamically unstable relative to the ground state. Its existence as a metastable phase makes it a subject of interest for researchers studying phase formation and structural evolution in transition metal systems.
Key Properties
