We are looking forward to exploring, discovering, and learning together as part of our drive to empower teams in our industry. In the past, we hosted Thermo Week, during which we focused on thermochemistry. Pyro Week has a broader scope, to address more of the needs that we have identified in our pyrometallurgy community.

I was privileged to attend the 22nd GTT User's Meeting these past two days. Due to international lockdowns, the conference was made virtual, so I was able to join from the comfort of my home.

I've been using LaTeX since 2013 now, and I still love it. It creates amazingly high-quality documents. The one irritating thing is the large number of files that the LaTeX compiler generates in the root directory of the document. How can I get rid of them?!

We took a bit of a breather last year, but in 2019 openSim is back! It will be our 5th symposium since starting at the University of Pretoria in 2014.

When you perform an equilibrium calculation, ChemAppPy will return the result as an object containing all the values from the calculation. You can inspect the values like you would with any regular Python object. But what if you performed multiple equilibrium calculations over a range of variables? How would you then easily inspect that results that would now be spread among multiple result objects?

We are excited to announce that a ChemAppPy training course will be held in June 2019 right before the annual GTT Users' Meeting! The 1.5-day course will start in the morning of the 25th of June 2019 and will be facilitated by Andrea Steyn from Ex Mente. The course will take place in the same venue as the Users' Meeting in Herzogenrath, Germany.

It has previously been observed that industrial high-titania slags display a compositional invariance, remaining close to stoichiometric M3O5. The present study focuses on this invariance and the phenomena which may cause it. The invariance was studied using thermochemical calculations and a mechanism is proposed for the observed behaviour.

The SGTE casebook is a valuable reference for those manufacturing steels and other materials, those using materials in high-temperature applications such as the power industry and in other areas such as microelectronics and lighting.
