BackgroundNanomaterials are suspected of causing health problems, as published studies on nanotoxicology indicate. On the other hand, some of these materials, such as nanostructured pyrogenic and precipitated synthetic amorphous silica (SAS) and silica gel, have been used for decades without safety concerns in industrial, commercial, and consumer applications. However, in addition to many in ...

Precipitated silica is prepared by condensing silica from dilute alkali silicate solution, which is accessible by digesting quartz sand with sodium carbonate or potassium carbonate. This alkali silicate solution is also called water glass. Silicic acid has a strong tendency to polymerize, converting silanol groups (SiOH) to siloxane bonds (Si ...

The typical way to mix fillers into rubber is by dry mixing, in which the filler particles (commonly carbon black or silica) are directly mixed with the dry rubber in a mechanical mixer before vulcanization. However, the inorganic silica filler is incompatible with certain rubbers, including natural rubber and styrene butadiene rubber.
