Composition and thermophysical properties of metallurgical plasmas - LTE calculations for PGM alloy smelting processes

This dataset contains two subsets: First - elemental compositions of the equilibrium gas phase over PGM alloy smelting metallurgical processes conducted in direct-current plasma arc furnaces at a range of slag temperatures between 1650˚C and 2500˚C. The processes are identified by the raw material used (ConRoast(r) dead-roasted PGM concentrate, or spent automotive catalysts) and the metallurgical reductant used (metallurgical coke, silicon carbide, ferrosilicon, or hydrogen). These were obtained from process simulations using thermochemical calculation software. Second - plasma composition and thermophysical properties at a range of plasma temperatures between 300 K and 30000K under local thermodynamic equilibrium conditions, as calculated using minplascalc software (https://github.com/quinnreynolds/minplascalc, version 1.0.2). All calculations are at atmospheric pressure, and use the elemental gas phase compositions for each slag temperature to define the mass conservation constraints.
