Abstract 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.
