Silicon slag generally refers to the remaining part of the raw ore refining, the slag also contains some content of silicon elements, can significantly improve the strength, hardness and elasticity of steel, improve the permeability of steel, reduce the hysteresis loss of transformer steel, high deoxidation rate.
Silicon slag is a byproduct of the production of silicon metal and ferrosilicon alloys. Though often regarded as waste, silicon slag holds significant value due to its unique properties and diverse applications in various industries. This article delves into the composition, production process, applications, and benefits of silicon slag, shedding light on its importance in modern industrial practices.
