Production of silicon powder
Resitec has extensive knowledge and experience in production of silicon powders and recycling of silicon materials generated during solar cell manufacturing in the photovoltaic (PV) industry. The company has built and operated several recycling factories in Norway and Asia. In Norway, Resitec is producing high purity, micronized silicon powder that is sold to advanced applications like batteries and ceramics (ReSiTec®1M Silicon). The material is recycled from PV wafer manufacturing, has very low contents of impurities, and the average particle size is approximately 1 micron. With its beneficial production cost and low CO2 footprint, Resitec recycled silicon is preferred to traditional crushed silicon for a number of applications.
Resitec has a broad international network within the silicon industry and is participating in several EU and EIT Raw Materials financed projects concerning silicon powders as important raw materials. Within these projects, Resitec generates a circular economy for side streams of the PV industry for development of new advanced materials.
