In Acta Chemica Scandinavica Gunnar Eriksson published a series of publications which culminated in 1971 in the third paper titled SOLGAS, a Computer Program for Calculating the Composition and Heat Condition of an Equilibrium Mixture. [1] In the abstract he stated: “A computer program named SOLGAS is described. SOLGAS is a program for calculating equilibrium […]
In connection with the Industry 4.0 initiative, tools for process simulation and process optimization are recently gaining in importance. In the context of metallurgy, its digitalization will work as an enabler of the „circular economy“ [1], by a combination of fundamentally-based process models, artificial intelligence, big data approaches and last by not least, guided by
From December 6th to December 9th 2021 we will host a four-day online course on Computational Thermochemistry and the FactSage software. On each day, the course will take half a day, from 1 pm to 5 pm Central European Time (CET). To participants who don’t already have FactSage installed on their PCs we will make FactSage

In recent years, there has been a continuous societal and industrial effort to promote the so-called „circular economy“. According to this paradigm, for producing engineering materials in general, and metals and alloys in particular, the chemical elements which are presently necessary in our economy should not be extracted from the so-called primary ores but instead

In this blog post we will see how to interpret the phase activity of a phase which does not form in equilibrium for a given temperature and pressure. For this, we will consider an Al-Cu alloy containing 0.01 mol% Cu at a temperature of 500°C and at a pressure of 1 atm and we will

Harvey and Gheribi[1] developed a thermochemistry-based model for the iron blast furnace. In their work, the corresponding process model was developed with a flowsheeting approach based on the connected local equilibrium reactors method, which was implemented using SimuSage, one of the very successful members the GTT’s product family. The model was constructed based on the

I have just attended the virtual DGM meeting which is concluded by the award presentation. My congratulations go to Katharina Esleben from University of Siegen and her co-authors, who have received the Werner-Köster award for their article Effect of Cr and Ni on the microstructural evolution in Co–Re–Cr–Ni alloys in the International Journal of Materials

Sometime ago a customer asked me how to find out if Ca2SiO4 is included in a certain database. Since the answer to this question can be really useful for customers in general, I decided to write this blog on the subject. We will define a substance with a defined chemical composition as a chemical species.
