碳热还原歧化法制备太阳能级硅的实验研究
Investigation of Production Solar Grade Silicon by Carbothermic Reduction and Disproportionation Method
摘要
Abstract
Using silica wastes and charcoal wastes which have been pretreated as raw material, high purity SiO gas can be formed by carbothermic reduction at high temperature, and SiO gas will be disproported into high purity silicon and silicon dioxide, then solar grade silicon can be prepared by separating silicon dioxide in HF acid via ICP method measurement. The new technique has some ad-vantages such as low energy consumption, environmental protection, simple production flow.关键词
