Congratulations to Dr Karin Fjeldstad Jusnes who successfully defended her thesis June 19th. Karin did an excellent and comprehensive presentation of the trial lecture: “Sustainable Low-Carbon Footprint Production of Si and FeSi” followed by the presentation of her PhD thesis “Phase transformations and thermal degradation in industrial quartz”.

100 persons registered for the online Silicon Conference June 16th

Screen shot zoom meeting. photoThe Silicon for Chemical and Solar Industry conference was originally going to be arranged in Trondheim from15th to 18th of June 2020. Due to the Covid-19 situation the confernce was changed to an integrated webinar with proceedings and online talks: A 3 hours plenary webinar, taped presentation of the rest of the papers, as well as the standard proceedings.

The aim of Silicon for the Chemical and Solar Industry conference is to discuss new development in Silicon Process Technology, Silicon Quality Assessment and Performance in the Subsequent Chemical Reactions including resource, energy and environmental issues.

The different processes from quartz to metallurgical and solar grade silicon, silicones or electronic silicon are strongly linked, and a sustainable process is dependent on a thorough understanding of the total process.  The development of production of solar grade silicon directly by metallurgical routes is also included.

Worldwide almost 100 participants from silicon industry, users and academia registered for the conference.



Congratulations Dr Azof!

Congratulation to Dr Fabian Imanasa Azof who successfully defended his thesis May 8th. Fabian did an excellent presentation of the trial lecture “Alumina quality, performance and applications: Dependence on ore quality and production process” followed by the presentation of his PhD thesis “Pyrometallurgical and Hydrometallurgical Treatment of Calcium Aluminate-containing Slags for Alumina Recovery”.

Spring meeting April 29th – A successful online webinar

April 29th SFI Metal Production organized the yearly Spring Meeting. Due to the extraordinary coronavirus situation we were not able to have a physical meeting this time. The traditional two-day spring meeting were replaced by an all-day online webinar. A positive effect was that the online solution enabled more participants from the industry and research institutions outside Trondheim to join the meeting.

to the webinar.

Ketil Rye, Process Technology Manager at Alcoa, congratulated the centre on a very well-organized agenda and a professional performance in the SFI Spring Webinar: “Alcoa had more than 15 direct participant and even more clustered around their computers to watch the latest news from the activities in Trondheim. Making the spring meeting as a webinar enabled a very good dissemination of results in spite of the present travel restrictions. Actually, in many respects the webinar format enabled a much better result dissemination than the traditional face-to-face meetings, as we could now invite participants throughout our world-wide company.” Another upside was the low cost of participation, as no time was spent in travel and the net time consumed was focused on the hours the webinar was open. 


Professors Merete Tangstad and Gabriella Tranell from SFI Metal Production have received funding for INTPART projects from the Research Council of Norway.
INTPART is a programme for International Partnerships for Excellent Education, Research and Innovation. The objective of the INTPART programme is to develop world-class research and education in Norway through long-term international cooperation with priority partner countries: Brazil, Canada, China, India, Japan, Russia, South Africa, the US, Germany and France. The purpose is lay a foundation that enables such research groups to develop longterm relations with strong academic groups in the priority countries.

How does materials relate to society?

Member of the SFI Scientific Committee, Professor Jean-Pierre Birat, has published a book with a holistic vision of the connection between materials science, the environment and society. The title of the book is Sustainable Materials Science - Environmental Metallurgy

In his book Birat stresses that it is no longer possible to think of materials from the restricted standpoint of Materials and Engineering Sciences.

The book examines how materials relate to society with complex metrics, but also how they generate eco-social services, and have agency along with the people who use them and invent them (Actor Network Theory). Materials are at the core of our societies and of our economies. They are part of pressing environmental challenges, but they also provide powerful answers. 

There are many excellent treatises on materials science and more on industrial ecology. However, the con-nection with the social dimension of sustainability is still rarely discussed and the pluridisciplinary cocktail of approaches used here is truly new.

In its pluridisciplinary approach the book is meant for students, researchers, engineers, and concerned citizens interested in how materials, nature and people interact. 

Jean-Pierre Birat is a metallurgist, who discovered environmental issues as a researcher with a major steel producer. He is a graduate of the Paris School of Mines and UC Berkeley. He has worked in France (IRSID, ArcelorMittal Research), Japan and Belgium (ESTEP), headed the ULCOS program and has been organizing the “Materials and Society” conferences for 14 years. He teaches the content of this book at the University of Science and Technology of Beijing.

Field trip to Alcoa Mosjøen for new students on alumina dissolution

As part of the kickoff for our new students on alumina dissolution, a field trip to Alcoa Mosjøen was organized in february.

Group picture in Alcoa Mosjøen

Raft formation Alcoa Mosjøen. PhotoGuided by Kim Ronny Elstad and Martin Grimstad, we were given a detailed tour in potrooms to see alumina feeding in action.

In order to gain insight of the real process, the crust was broken, enabling visualization and video recording of raft formation – as performed by summer interns earlier.

Results from the last year were showcased by PhD student Sindre Gylver.  Our BSc students Simen Aase, Simen Bekkevoll and Sigmund Forberg and MSc student Maria Frenkel participated in good discussions with representatives from Alcoa Mosjøen.

Activities will be followed up during the coming months by our students, further probing the behaviour of alumina in primary aluminium production.

Seminar at Alcoa Mosjøen – December 5, 2019

A workshop on innovation research in the aluminum industry was organized at Alcoa, Mosjøen, December 5th. Alcoa is one of the SFI Metal Production industry partners. A delegation from NTNU and SINTEF visited Alcoa to discuss progress in ongoing research.
Visitors from Trondheim (NTNU and SINTEF) were representatives from the SFI management and researchers from the project HighEFF.

Project managers presented recent results, and future plans were discussed in groups with participants from both organizations. 

Alcoa was a great host for the delegation from Trondheim. The seminar program also included a tour on the smelter site, highly appreciated by participants visiting Alcoa for the first time. We are looking forward to continuing the collaboration and wish to thank Alcoa for receiving us and making the seminar a success.

New Postdoctor at SFI Metal Production - Shokouh Haghdani

Shokouh Haghdani started as a Postdoctor at the Centre in December 2019. Shokouh’s preliminary project title is “Influence of structure on slag viscosity”, and Professor Kristian Etienne Einarsrud is her supervisor.

Shokouh got her PhD from the chemistry department at NTNU.

The project aims at developing thermodynamic viscosity models for slag systems. The models will be linked to the structure of slags using Raman spectroscopy that characterizes internal structures experimentally. In addition, a rotational viscometer will be employed for measuring viscosity (when applicable) to validate viscosity models. We would like to perform these steps for three industrial systems, namely Mn-, Ti- and Si-related slags.

The Dross and Packaging Recycling workshop - a success!

The international Dross and Packaging Recycling Workshop was arranged May 15-16 in Trondheim as a part of SFI Metal Production’s activities. When announced this event, this workshop seemed to be pretty popular and we needed to minimise number of participants to around 40 in order to get a productive workshop. Except from SINTEF and NTNU twelve companies: Hydro, Alcoa, Novelis, Linde Gas, Norsk Metallgjenvinning, Gränges, Kavli, Metallco, Infinitum, Real Alloy, Constellium and Trimet Aluminum and two interest organisations: European Aluminium and Aluminium Association participated in this workshop.

The goal for these two days was to review recent problems and developments in dross and aluminium packaging recycling to a better understanding where more research or technical effort is most needed.

The enthusiastic participants worked hard during these two days and carried out four workshop session together. The first on Recyclable aluminium including collection, the second on Remelting Technologies and the third on Dross, Saltcake and the fourth and last on Quality and use of recycled Aluminium & Dross.

Anne Kvithyld, in your opening talk you presented the goal for this workshop. Did you reach them? “Yes, I feel we succeeded very well in discussing problems, developments and constraints. I am humble to expert group knowledge and amazed by their engagement.”

The program shows a push against the future perspective in all the presentations and workshop sessions. Do you have something of special interest you want to mention in this connection? "Generally new legislation, old problems – with the need to test out several upcoming technologies”

The organiser at SINTEF Industry, Anne Kvithyld and Berit Fossum, did a tremendous work with this workshop and got a lot of positive feedback in the finishing questionnaire. Thanks to the participants and the organisers for making this workshop to a success!
