摘要
本文考察了硼的引入对聚硅酸稳定性的影响 ,利用透射电镜及红外光谱观测了其形态结构。结果表明 ,在强酸性条件下 ,适量硼的引入有利于聚硅酸的稳定 ;硼参与了聚硅酸的聚合反应 ,改善了聚硅酸的形态结构 ,从而阻缓了它的进一步胶凝 。
Effect of introducing boron on the stability of polysilicic acid is investigated in this paper.Its morphology and structure are analyzed by transmission electron microscope and infrared spectrometer.It is found that under strong acid condition,introducing proper amount of boron can increase stability of polysilicic acid.Boron takes part in the polymerization reaction of silicic acid and chages its morphology and structure,consequently delays its further aggregation and increases its stability.
