[ 1 ] - Synthesis of nanosilica from silica fume using an acid-base precipitation technique and PVA as a nonionic surfactant

The purpose of the present study was to synthesize and characterize nanosilica from alkali-extraction of silica fume under controlled conditions using poly (vinyl alcohol) (PVA) as a dispersing agent. The dissolution efficiency of silica fume was affected by various factors such as concentration of the reagent, reaction time and temperature. A maximum dissolution efficiency of 91% was achieved ...
