【摘要】：以氨水+二氧化碳脱硫的脱硫铅膏为原料、淀粉为碳源,进行糊化活化后,在氮气保护下置于管式炉中煅烧制备铅炭材料。考察了淀粉与铅膏的质量比、煅烧温度、煅烧时间对产物的影响,并利用热重分析(TGA)、X射线衍射(XRD)、透射电镜(TEM)等分析手段对产物的成分、形貌、结构和粒径分布进行分析,结果表明,淀粉与铅膏质量比为1∶1时,在450℃下煅烧2.5 h制得的铅炭样品基本无团聚现象,铅或铅的氧化物颗粒均匀地分散在碳基质中,粒径分布窄,平均粒径为11.69 nm,为制备优质的铅炭电池负极材料提供了一种新的途径。
[Abstract]:The lead desulphurization paste from ammonia and carbon dioxide desulphurization was used as raw material and starch as carbon source. After gelatinization and activation, lead carbon was calcined in a tube furnace under the protection of nitrogen. The mass ratio of starch to lead paste and calcination temperature were investigated. The effect of calcination time on the product was analyzed by thermogravimetric analysis (TGA), X-ray diffraction (XRDX), transmission electron microscopy (TEM), etc. The composition, morphology, structure and particle size distribution of the product were analyzed. The results showed that the mass ratio of starch to lead paste was 1:1. The lead carbon samples calcined at 450 鈩，
