A precursor stoichiometry calculator for solid-state synthesis. Give it a target composition, the precursors you have on hand, and a total quantity, it tells you exactly how many grams of each to weigh out.
- Mol% or Wt% target composition input
- DO-NOT-balance rules for real decomposition chemistry (carbonates, nitrates, hydrates)
- Doping-series batch mode: solve several compositions in one pass
- Precursor autocomplete library
- Solve by target product mass or by total precursor mass, in mg or g
- CSV/print export, saveable and shareable recipes
- Literature-reference lookup for the same composition family
- Persistent calculation history
Originally ideated from ChemSolve's core idea, extended with all of the above.
Plain HTML/CSS/JS, no build step, no dependencies. Clone the repo and serve it with any static server, e.g. npx serve, then open http://localhost:<port>/. Internal links use clean paths (/calculator, /history, /contact), which need a server to resolve, plain file:// double-clicking won't route between pages correctly.
node test_logic.js runs a standalone regression suite against the core formula-parsing and balance-solving logic.
