Determine the Average Particle Size of Silica Sol
Keyword(s):
At present, the methods of analysising the average particle size of silica sol are the intuitive analysis, such as analysising the size distribution and morphology of the particle by the laser particle size instrument and the transmission electron microscopy. But some of the small particles tend to be ignored. Using the classical chemical titration method and BET to auxiliary analysis can make the date more complete. Through the comprehensive analysis with the four methods, found that longer reaction time have the effect of purification of sol system.
