At the SINTEF/NTNU facilities, we offer a range of laboratory and pilot-scale equipment and methods for metallurgical production and refining of silicon feedstock. These include:

• Rotary plasma furnace for production of high purity SiC from high purity raw materials
• Single phase electric arc furnace for pilot scale production of silicon metal
• Direct production of Si by molten salt electrolysis
• Refining
• By filtration
• By casting
