Computational thermodynamics: Meaningful phase diagrams without experimental input? — •Sebastian Schwalbe1, Kai Trepte2, and Jens Kortus1 — 1TU Bergakademie Freiberg, Institute for Theoretical Physics, Germany — 2Central Michigan University, Department of Physics, USA
Ab-initio thermodynamic data sets, especially isobaric heat capacities, calculated within our
new MD approach for lithium silicides [1,2] are presented.
Further, a theoretical phase diagram is discussed, where the melting points are determined using a method based on the evaluation of diffusion behaviour.
The key property, the so called diffusion coefficients, and the melting points themselves are compared with experimental data.
