<p>In this study, the reduction of dolime via the silicothermic method was investigated, focusing on the effects of reduction temperature and reductant ratio on the reduction rate and phase transformation within the dolime-ferrosilicon mixture. The findings demonstrated that the degree of dolime reduction increased with both higher reduction temperatures and greater ferrosilicon ratios. It was observed that Fe in the ferrosilicon reductant does not actively participate in the reduction reactions. Instead, silicon engages in the reduction process through the formation of a liquid Ca–Si intermediate compound. The reduction can proceed via both solid–liquid and solid–gas reactions, with Ca acting as an effective reductant. However, the progressive formation of larger Ca₂SiO₄ products around the ferrosilicon particles creates a barrier that gradually decreases the reaction rate over time.</p>
