摘要: 進行了配碳量、溫度、時間和顆粒大小及試樣形式對碳還原鋯英石中SiO₂的實驗研究,得到相應脫硅率的影響規律。理論上,脫硅率的極大值可達到97.22%。碳還原鋯英石的表現反應活化能,在1600~2000℃溫度范圍內為282.04kJ/mol。鋯英石被碳還原的限制環節是鋯英石的熱分解,而不是它裂解成SiO₂之后再與碳的反應。

Abstract: The influence of carbon content, temperature, time, particle size and from of samples on the reduction of SiO₂ by carbon in zircon were studied. The effects of these factors on the ratio of desilica from zircon were obtained. The maximum value of this ratio could reach to 97.22% theoritically. The apparent activation energy for the reaction of zircon with carbon was 282.04 kJ/mol (1600~2000℃).Besides, the limiting step of reduction of SiO₂ in zircon was the heat decomposition of zircon, not the reaction of SiO₂ with carbon after decompostion of zircon.
