    A STUDY ON THE FORMS AND POLYMERIZATION KINETICS OF SILICIC ACIDS IN STRONGLY ACIDIC ELECTROLYTE SOLUTIONS.

    • Studies have been made on the forms of silicic acids and their transformations in strongly acidic electrolyte solutions with Si content of 150 mg/1 and l00mg/1 after different heating treatments and the addition of various flocculating agents. The results show that the polymerization of low molecular weight silicic acids are close to a third order reaction, with an apparent kinetics constant which is roughly proportional to the concentration of hydrogen ion. Although the flocculating agents have little effect on the polymerization kinetics behavior of low molecular weight silicic acids, they do increase the polymerization rate of the intermediate molecular weight silicic acids. The polymerization kinetics of silicic acids can reasonably be described by a consecutive reaction.
