impurities coming from the silica, reductors and electrodes of the arc furnace [10]. High-purity silica sand can pro-duce high quality MG-Si. However, the purity silica sand from different sources exhibits significant differences. Only a small portion of the silica sand can be applied directly to the high-purity silicon production.
The iron impurities in silica sand mainly exist in various forms such as muscovite, pyrite and iron oxides. The existence of iron impurities greatly reduces the use value of silica sand and affects the quality of products. Therefore, it is very important to remove iron from silica sand. This article will take you to learn more about these 6 ...
