It is for the first time to analyze the polymerization degree of [SiO4] and [AlO6] of FBC ashes by IR,and the results show that the polymerization degree of [SiO4] and [AlO6] of FBC ashes is lower than that of PC fly ashes, especially the former.

• 首次用红外光谱对固硫灰渣的硅酸盐阴离子聚合度进行了分析,发现固硫灰渣[SiO4]和[AlO6]聚合度均低于粉煤灰的,尤其是[SiO4]。
