Thermodynamic data bank: The principles, organization, and structure of software

The structure and special features of a software for work with a data bank are described. A method for storing thermodynamic information about mineral and gas phases and solution components is suggested. The purpose of the creation of the data bank was the provision with the initial thermodynamic data and programs that minimized the Gibbs energy for the solution of physicochemical simulation problems and the construction of mineral equilibrium diagrams. The possibilities of the software were demonstrated for the example of the construction of mineral equilibrium diagrams for minerals containing rare-earth metals.
