There are many ways to classify silica sol, which can be classified according to particle size or pH range

There are three main categories of silica sol according to the pH value:

1. The pH value between 2.0to4.0 is acidic silica sol. Acidic silica sol with small particle size is mainly bluewhite transparent liquid, and acidic silica sol with large particle size is milky white liquid.

2. The pH value between 7.0-9.0 is neutral silica sol,
