Sol-gel 공정에 의한 Silica sol의 합성 및 특성
Synthesis and Properties of Silica Sol by Sol-Gel Process
Reaction completion time was investigated to measure OH/CH ratio as reaction time at 25℃. In 50 and 60 minute reaction was completed in 1.0 ratio that was reached equilibrium state. In another method, equilibrium state was investigated by measuring volume% of C2H5OH. From 40 to 50 minute, that was reached at 61.6 of volume%. Mean molecular weight(Mw) of sol solution was about 7,000.
