Process Metallurgical Laboratories

Modern production of high quality metallic materials requires advanced knowledge of pyro-metallurgical processes. SINTEF optimises metallurgical processes and raw materials, using a combination of laboratory scale and pilot scale experimental techniques, combined with thermochemical modelling.

Contact person

The equipment in the SINTEF laboratories can simulate metallurgical processes from raw material to metal. We can test the performance of different raw materials (carbon materials, quartz and Mn-ores) in metallurgical processes. SINTEF has key competence in electric arc / submerged arc production of Manganese, Silicon and Ferrosilicon alloys. Plasma production of Silicon Carbide and carbon materials such Carbon Black and Carbon Nano Tubes are also fields of expertise at SINTEF.
