Tellurium-assisted solid-phase thermal transformation produces pure, homogeneous violet phosphorus powder within 7.8 hours, overcoming sluggish growth kinetics of crystalline red phosphorus phases.
- Why it matters: Violet phosphorus is the thermodynamically most stable crystalline allotrope, but its formation is limited by slow growth kinetics, leaving a kinetic bottleneck unresolved.
- What they did: The authors used a Te-assisted thermal transformation with a 500°C hold (3 hours) and developed a pressure-gradient transport method to indirectly measure vapor pressure in the Te-assisted system.
- The result: A proposed evolutionary model links Te to lowering the kinetic barrier by reshaping the transition-state energy landscape, making VP the kinetic and thermodynamic product and enabling mechanistic insight into polymorphic phosphorus synthesis.
