The aim of this work is the purification of MG-silicon powder using a method combining acid leaching and thermal annealing. This study describes experiments conducted using a tungsten lamps furnace (rapid thermal processing, RTP) to purify silicon powder under a controlled atmosphere. The process facilitates the segregation of impurities to the surface of the silicon powder, where they can be extracted through partial dissolution in acids. The purified silicon was analyzed via Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). The major impurities identified in the silicon powder included Al, K, Fe, Na, Ca, Mg, and B. Subsequent to the purification process, the concentration of these major impurities was found to have significantly decreased, thus enhancing the quality of the silicon for photovoltaic applications. This research highlights an effective method that could contribute to meeting the increasing demand for high-purity solar-grade silicon in the rapidly growing photovoltaic industry.
