Fumed silica normally classified into two classes: treated and untreated (also known as hydrophilic and hydrophobic). Normally the hydrophilic one is cheaper than hydrophobic. The particle size of fumed silica is around 7~40 nm. The most commonly used unit is BET surface area (m 2 /g), a 40′ HQ container can load ~4 Mt fumed silica inside.
