Phase Diagram Generation With Convex Hull Thresholds for Metastable Compounds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional phase diagrams are limited to representing thermodynamically stable compounds, making it difficult to design and visualize metastable compounds, which are energetically unstable but locally stable, and thus challenging to synthesize.
Innovation Solution
An information processing method that acquires energy information indicating the threshold of thermodynamic convex hull energy and generates phase diagrams that include both stable and metastable compounds by adjusting the threshold, allowing for the visualization of metastable compounds.

Engineering Contradiction Analysis
1Loss of information
If conventional phase diagrams are used to represent only thermodynamically stable compounds, then the phase diagram is simple and clear, but it cannot visualize or facilitate design of metastable compounds
Solution Approach 1:
The phase diagram is segmented into multiple layers: a base layer showing thermodynamically stable compounds and an overlay layer showing metastable compounds. This segmentation allows both stable and metastable compounds to be visualized simultaneously while maintaining the clarity of the stable compound framework, thus preventing information loss about metastable compounds without overly complicating the overall diagram structure.
Solution Approach 2:
The patent introduces a new dimension by adding energy information (thermodynamic convex hull energy) as a visual parameter in the phase diagram. Metastable compounds are represented with additional visual cues indicating their energy relative to the convex hull, effectively adding an energy dimension to the traditional composition-temperature phase diagram space.
2Loss of information
If phase diagrams include both stable and metastable compounds with energy information, then metastable compounds can be visualized, but the visual clarity and ease of understanding decreases
Solution Approach 1:
Different visual styles are applied to different regions of the phase diagram: stable compounds are shown with simple, clear symbols and lines, while metastable compounds are shown with distinct visual markers indicating their metastable nature and energy level. This local differentiation allows users to quickly identify and understand metastable compounds without making the entire diagram overly complex.
Solution Approach 2:
The patent uses color coding to distinguish between stable and metastable compounds, and to indicate energy levels. Different colors or shading intensities represent different thermodynamic convex hull energy values, allowing users to rapidly assess the stability and energy characteristics of compounds at a glance, maintaining ease of understanding while conveying rich information.
