We will offer on April 27th and April 28th of 2020 a two-days course on Computational Thermochemistry and on the FactSage software. The course is open to all interested parties. The course fee is 550 Euro (German customers please include 19% VAT) and includes teaching materials. We will accept a minimum of 2 and a …
The loss of copper in the converting process through its incorporation to the converter slag represents a major problem in the copper metallurgy. There are two important mechanisms for this phenomenon: the physicochemical and the mechanical one. The mechanical mechanism, i.e. the mechanical entrapment of matte or of metallic copper inside the slag, is by …

Mats Hillert has shown [*] that what is called a Phase Diagram is derivable from a projection in a so-called Property Diagram. The (molar) Gibbs Energy as the property is plotted along the z-axis as a function of two other variables x and y. For binary systems, for example, T equals y and the mole …

In the 2nd part of this blog post, we will see how to export the data we generated in the Part I to Excel. Let us start with the Results window from the last blog. On the menu bar, we click on “Output”->”Save or Print”->”Save or Print As” Figure 1 A window will pop up, …

A customer has asked me: “Is it possible to export/import data to and from FactSage? For instance, I would like to do a series of calculations for different initial chemical compositions of the system and it would be very useful to import all the compositions automatically from an Excel table into FactSage”. Yes, it is …
Our users’ meeting from 26th to 28th of June is approaching quickly! The users’ meeting itself starts on the 26th of June at 13:00h and goes until 12:00h on June 28th. Many colleagues from the industry and academia already registered to contribute with presentations and we are looking forward to the many interesting talks showing …
In a series of posts, we will focus on the relation between phase diagrams, Gibbs energy functions and activities. Let us begin with the Al-Cu phase diagram at a temperature of 500 °C. In this blog post we will work exclusively with the FactSage Education Package. Let us suppose we have generated an Al-Cu phase-diagram …

A customer has asked me: “How can I include an experimental point on a figure generated in FactSage ?”. The procedure is relatively simple. Suppose that you have generated a curve in FactSage like the one below. Representing the Molar Gibbs Energy of the γ phase in the Fe-C system at 1000°C as a function …
It is a common misconception that thermodynamic calculations can only be used for processes that are in equilibrium. In fact, there is a lot to learn from an Integrated Thermodynamic Databank System like FactSage even if you are far away from equilibrium! As example we consider the popular Fe-C system: If you choose all phases …

FactSage contains many modules. The major ones for daily work are Equilib and Phase Diagram. Phase Diagram permits the calculation of phase diagram sections for systems with any number of components. Components can be elements, compounds or even arbitrary compositions. For a phase diagram calculation, first the components of interest have to be defined. Then, the possible …
