Abstract
- Freeze/thaw test for silica stability against aggregation.
- Both effects of solution pH and quantity of PVP addition are investigated.
- In alkaline condition, small amount of PVP is needed to stabilize silica colloids.
- In acid condition (pHÂ =Â 4), PVP addition promotes aggregation instead.
