11/04/2020  Crystalline metallurgical silicon nanopowder was successfully produced from Tunisian silica sand by magnesiothermic reduction. Silica sand was first transformed into silica powder via a specific chemical process. The produced silica powder was reduced by magnesium granules at a temperature range of 500–800 °C. Thermal analysis shows that a low-temperature ramp rate (5 °C min−1) allows ...
