The white carbon black powders were prepared through carbonation of water glass. The UV-vis spectra and 29SiNMR were used to characterize the configuration of silicon atoms before and after polymerization of silicic acid. The results indicated that the luminousness decreased as the reaction progress. The polymerization process was divided into three stages which include slow polymerization, fast polymerization and the end of polymerization. The signals of 29SiNMR demonstrated that the silicate of raw material was in a ring multimer. In the fast polymerization phase, 29SiNMR signal was split into 5 peaks which indicated there were a complex configuration resulted from silicon atom in different chemical environment including monomers, multimers and hydrated ions. After completion of polymerization, the 29SiNMR signal presented a single peak at −113 ppm with two shoulder at −98 and −93 ppm, indicating that the silicic acid polymerized to form homogeneous Q4 configuration. TEM images revealed that the white carbon black powders were spherical particles resulted from homogeneous polymerization of ring nucleus. The effects of pH value, temperature on polymerization rate of silicic acid were studied as well. In alkaline system, the polymerization rate of silicic acid decreased with the increase of pH value. Higher the reaction temperature, shorter the gelation time of silicic acid. The growth kinetics of hydrated silica was investigated and the apparent activation energy of particle growth of hydrated SiO2 was 43.377 kJ/mol in the first polymerization stage.
