: It serves as an anti-caking agent to keep powders free-flowing and is used as an excipient in tablet manufacturing to ensure consistent dosage. Safety and Handling

Fumed silica is a non-crystalline (amorphous) form of silicon dioxide ( SiO2cap S i cap O sub 2

: One of its most valued traits is its ability to change the viscosity of liquids. It creates a "thixotropic" effect—liquids become thinner when stirred or agitated but thicken back into a gel-like state when left still. 112945

The number is the primary CAS registry number for fumed silica (also known as pyrogenic silica), a versatile synthetic material used extensively across modern industry. The Science of Fumed Silica

: It acts as an anti-sagging agent, preventing paint from dripping off vertical surfaces. : It serves as an anti-caking agent to

: It is used in skincare and makeup for its light-diffusing properties and to improve texture.

While fumed silica is not classified as a carcinogen, it is an due to its fine particle size. Prolonged or high-level exposure can irritate the respiratory system and eyes. Consequently, safety protocols typically require the use of protective masks and ventilation when handling the dry powder in industrial settings. CAS 112945-52-5: Silica, amorphous, fumed, cryst.-free The number is the primary CAS registry number

) produced through . In this high-temperature process, silicon tetrachloride is vaporized in an oxygen-hydrogen flame, creating microscopic droplets of molten silica. These droplets fuse into branched, chain-like structures called "secondary particles," which then agglomerate into the light, fluffy white powder found in industrial sacks. Key Physical Properties
