112945 Review

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

: Fumed silica has an incredibly high surface area-to-mass ratio, typically ranging from

: It is used in skincare and makeup for its light-diffusing properties and to improve texture. 112945

: It is generally non-reactive, making it a safe additive for a variety of sensitive products. Industrial Applications

Because of its unique ability to thicken and reinforce, fumed silica is used in a vast array of consumer and industrial goods: 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

: It provides structural reinforcement and controls flow during application. Industrial Applications Because of its unique ability to

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