About the summer school
The second summer school on silicon production will be organized by NTNU from the 18 to the 21 June. While the first summer school, organized in 2010, focused on Sog-Si, the theme of this summer school will be an in-depth course on metallurgical silicon production. During a three day lecture series fundamental knowledge and theory describing the process of producing silicon will be given by several lecturers from SINTEF, NTNU and the industry. A visit to Elkem Thamshavn will be arranged on the fourth day.

A visit to Elkem Thamshavn will be arranged on the fourth day.
Norway's position as a world-leading producer of metallurgical silicon gives access to a wide range of talented lecturers. Subjects will cover the whole process chain from raw-materials, through furnace design, reaction pattern to finished product, all vital to the silicon process. Special emphasis will be given to the reaction patterns inside the furnace and also the large scale environmental considerations that need to be made when producing silicon.
The goal of this course is to provide participants with the necessary knowledge to operate and understand silicon production. Better process understanding will lead to higher silicon yield and less pollution and waste. An economic optimum operating condition is achieved only through knowledge of all aspects of the process. We also believe that the environmental aspects of silicon production will become increasingly economical important. Governmental authorities are pushing for reduced emissions of greenhouse gases such as CO2, NOx and PAHs and reduced emissions quotas and increased quota prices justify an increased focus on possible climate-friendly measures.
The summer school will be an excellent venue to catch up on the latest research advances at NTNU and SINTEF, and to brush up on old knowledge. The social arrangements will provide a valuable opportunity to build networks across the companies. There will be arranged a city walk of Trondheim and dinner, in addition to the visit to Elkem Thamshavn. Don't miss out on this event!
Fee and registration form
The fee will be NOK 7 000. The fee will cover course materials, the excursion to Thamshavn on Thursday, lunches, beverage breaks and dinner/activities on Tuesday and Wednesday, but no board or other meal expenses. Hotel is not included.
Register at your earliest convenience. The attendance is limited to 50 participants and applications are accepted in the order of receipt. The registration will open within the first week of March.
