Hydrophilic Vs Hydrophobic Fumed Silica Application

Fumed silica also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles.The resulting powder has an extremely low bulk density and high surface area. Its three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickener or reinforcing filler.

Physical and Chemical Properties
Appearance: White, fluffy, amorphous powder
Density: 160–190 kg/m³
Surface Area: 50–600 m²/g, depending on type
Particle Size: 5–50 nm
Chemical Stability: Insoluble in water and most acids, soluble in hydrofluoric acid; inert under normal conditions
Thixotropic Behavior: Forms a network that increases viscosity at rest but flows under stress, useful for rheology control
