SiO_2—C系的高温反应热力学,是工业硅熔炼的主要理论基础,通过对此问题的研究,使我们可进一步认识工业硅熔炼的高温反应规律与机理,并能借以找出工业硅熔炼的最佳条件,以便提高生产技术水平与生产效率。为此,本文将讨论如下三个问题:一、SiO_2—C系 The thermodynamics of high-temperature reaction of SiO_2-C system is the main theoretical basis of industrial silicon smelting. Through the study of this problem, we can further understand the high-temperature reaction rules and mechanism of industrial silicon smelting, Good conditions, in order to improve the level of production technology and production efficiency. To this end, this article will discuss the following three issues: First, SiO_2-C system
