Changes in Quartz During Heating and the Possible Effects
Oct 10 2014 · In Si and FeSi production the main Si source is SiO2 in the form of quartz. Reactions with SiO2 generate SiO gas that further reacts with SiC to Si. During heating quartz will transform to other SiO2 modifications with cristobalite as the stable high-temperature phase. Transformation to cristobalite is a slow process. Its rate has been investigated for several industrial quartz sources and
