Welcome to the online formation energy predictor. This tool deploys data mining models to predict the formation energy (a measure of stability; more negative values implying more stable) of a material based on its chemical composition. The predictive models deployed here have been built on hundreds of thousands of Density Functional Theory (DFT) calculations on crystalline materials from the Open Quantum Mechanical Database (OQMD), and run many orders of magnitude faster than DFT.
In order to use this tool, please provide the list of chemical compositions in the text box below, and click Submit. Please ensure that each chemical formula respects the charge balance condition with common oxidation states of individual elements. The elements greyed out in the periodic table below may not be used. The predictions from different models are presented in a table (sortable by clicking the header).
