Fig. 3 shows a typical TG-DTA curve of the silica powder modified by 0.5 ml of HTMS after ball milling for 24 h. The DTA curve showed two peaks at approximately 130 and 300 °C. The first endothermic peak corresponds to the loss of physically adsorbed and/or hydrogen-bonded water from the silica powder [22].The second exothermic peak …

The form of silica can change in a process depending on how the silica is treated. Chemical treatment, as well as high temperature processes or treatment of amorphous silica, can create crystalline silica. For example, when diatomaceous earth, an amorphous form of silica, is calcined (heated to a high temperature), crystalline silica …

of around 1800°C. The silica produced by the gas phase hydrolysis is extremely fine and the reaction gases form aerosols which cannot be aggregated[9]. Therefore, the silica aerogel in the gaseous phase is first aggregated into larger silica particles in an aggregator, and then the produced silica semi-finished products are collected in a

Optimization of Silica Dispersion Preparation. Silica powder can be generally ground in a dry or wet ball milling process. However, dry ball milling gives larger silica aggregates because of the interactions between silica particles by H-bonding of silanol groups. In wet ball milling, silica is dispersed in water during the grinding.
