What formula formats are supported?
Matproof supports standard chemical notation (LiFePO4), fractional stoichiometry (LiNi0.8Co0.1Mn0.1O2), and parenthetical groups (Na3V2(PO4)3). Formulas are automatically normalized for database lookup.
How accurate is the cost estimation?
Cost estimates are based on USGS 2025 commodity prices for raw elements. Actual material costs depend on purity, form, supplier, and quantity. Our estimates provide a baseline for comparison between candidates.
What does "energy above hull" mean?
Energy above hull (Ehull) measures thermodynamic stability. A value of 0 means the material is on the convex hull and thermodynamically stable. Values up to ~0.025 eV/atom are considered metastable and potentially synthesizable.
Which stability database is used?
We query Materials Project first (most reliable), then OQMD, then AFLOW as fallbacks. The response indicates which database provided the data. All use DFT calculations with similar accuracy.
