About the TCS Metal Oxide Solutions Database (TCOX)

TCS Metal Oxide Solutions Database (TCOX) is a thermodynamic and properties database used for application to slags and oxides. The intended application is for solid and liquid ionized materials, for example oxides or sulfides. Despite the name of the database, it can also be used for fluoride and sulfide systems without oxygen. The database integrates thermodynamic data plus properties data for molar volume, viscosity for ionic liquids, surface tension, electrical conductivity for ionic liquid, and thermal conductivity for the ionic liquid.

Carbides and nitrides are included in the database. However, neither intermetallic compounds and phases, nor ordered BCC, FCC, and HCP, are included.

Common applications of the database include:

  • Development of ceramics
  • Slags
  • Refractories
  • Metallurgical processing (for example slag and liquid metal interactions)
  • ESR slags
  • Materials corrosion
  • Thermal Barrier Coatings (TBC)
  • Yttria-Stabilised-Zirconia (YSZ)
  • Solid oxide fuel cell materials
  • Sulfide formation
  • Dephosphorization and desulfurization
  • Recovery of lithium in the pyrometallurgical processing of lithium-ion battery recycling

The database is compatible with the Process Metallurgy Module, an Add-on Module used for advanced calculations involving slag, metal, and gas. The Module is primarily designed for application to steelmaking and steel refining processes including converters, such as basic oxygen furnaces (BOF), electric arc furnaces (EAF), ladle furnace (LF) metallurgy, and more. The Module can also be applied to other metallurgical processes.

Visit the website Application Examples → Process Metallurgy page for more background information as well as more in depth analyses of this and other examples. Also visit the Process Metallurgy Module page to access resources such as training videos, presentations, publications, webinars, and much more.

There are examples available to both demonstrate the validation of the database and to showcase the types of calculations that can be used for different materials or application area such as process metallurgy, heat treatment, and more depending on the database.

About the Database Examples

Some use case examples of how the TCOX14 database can be used include the following.

  • The intended application is for solid and liquid ionized materials, e.g. oxides or sulfides. This could be development of ceramics, slags, refractories, metallurgical processing (e.g. slag and liquid metal interactions), ESR slags, materials corrosion, Thermal Barrier Coatings (TBC), Yttria-Stabilised-Zirconia (YSZ), solid oxide fuel cell materials, sulfide formation, dephosphorization and desulfurization.
  • This database can be used for fluoride and sulfide systems without oxygen.
  • The liquid phase is described from liquid metal to oxide and/or fluoride, i.e. no pure liquid oxygen or fluorine is modeled.
  • For sulfur, the liquid phase is described all the way from metal to sulfur.

It is possible to combine several databases to make calculations using Thermo‑Calc.
