Li2O and P2O5 in the GTOx thermochemical database

/ Databases, GTT /
GTT's Logo

The GTOx oxide database was developed in-house at GTT-Technologies and in close cooperation with Forschungszentrum Jülich, IEK-2, specially with Elena Yazhenskikh. The thorough literature review  was performed concerning phase diagram information and thermochemical experiments (enthalpies of formation and transformation, component activities, oxygen partial pressures etc.). GTOx includes a description for different combinations of oxides, e.g. […]

GTT at ASK 2018

/ Conference /

The 32nd “Aachener Stahlkolloquium“ (Aachen Steel Colloquium) has just started. This year’s topic is “Metallurgy in Transition 4.0” and the topics include digitalization, biofuels and hydrogen, big data and casting. It is clear that these aim at society’s needs for sustainability and low CO2-emissions while making sure that steel can still be produced in high-wage

9th International Freiberg Conference on IGCC & XtL Technologies – Closing the Carbon Cycle

/ Conference /

I’m currently attending the 9th International Freiberg Conference on IGCC & XtL Technologies – Closing the Carbon Cycle, which takes place in Berlin. Over the years the International Freiberg Conference on IGCC & XtL Technologies has grown into a sizeable and very well-organized event that brings together the integrated gasification combined cycle and synthetic fuels

Why does GTT start a blog?

/ General /

“In this house, we obey the laws of thermodynamics!” – Homer Simpson.   We at GTT completely agree: The laws of thermodynamics are the solid foundation on which we can build understanding of materials and processes. Not all materials and processes are in equilibrium, but there are also many options to calculate constrained equilibria and
