Characterization of Nano-crystalline Metallurgical-Grade Silicon Prepared from Rice Husk Ashl-grade silicon (MG-Si) suitable as a solar-grade silicon material. Processing rice husk ash into MG-Si requires careful control of temperature and time during the initial ash-making procedure and subsequent refinement to remove impurities. In this work, silica of between 95.24 and 98.03% has been p
