Silica density

Precipitated silica has both internal and external surface area, which allows for easy adsorption of liquids, among other qualities. Primary characteristics include:

Tapped Density and Specific Gravity
The specific gravity of precipitated silicas is approximately 2.1. This is a chemical property of silicon dioxide manufactured by this type of process. The resulting solvated weight per gallon (bulking value) is about 17.5 pounds. The density of precipitated silicas can range from about 70 g/l to 300 g/l depending on the type of silica and at what point the material is sampled. Unmilled grades of precipitated silicas will have higher densities than milled products, since milling reduces both particle size and density.
