摘要
初步探讨了用工业固废粉煤灰制备白炭黑的方法。依此法,粉煤灰经激活、酸浸、陈化、除杂等工艺,制备出SiO2纯度达91.7%的白炭黑,其化学式为SiO2·1/7H2O,品质标准符合HG/T3601。
The technique of preparation of SiO2·nH2O from a solid waste, fly ash,was studied generally. The product with purity w=91.7% was obtained by the process of activiation, acid treatment, and purification,etc. The formula of the product is SiO2·1/7H2O,the quality of the product can meet the repuirement of Chinese standard HG/T3601.
