Precipitated Silica is a form of silicon dioxide (SiO₂) that is produced through a chemical process where silica is removed from a solution, typically by precipitation. It is widely used in various industries due to its unique properties, such as high purity, large surface area, and stability.
Chemical Composition: SiO₂
Appearance: Typically amorphous or crystalline powder
Purity: Can range from 90% to over 99.9%
Surface Area: Highly porous, with surface areas ranging from 300 to 3000 m²/g depending on the production method
Density: ~2.2–2.3 g/cm³
Thermal Stability: Can withstand high temperatures up to 1000°C
Electronics: Conductive fillers, insulators, and semiconductors.
Automotive: Tires (as a reinforcing agent), brake pads, and exhaust systems.
Construction: Lightweight concrete, insulating materials, and sealants.
Medical: Drug delivery systems, dental materials, and wound dressings.
Cosmetics: Abrasives, face masks, and skincare products.
Industrial: Filtration media, catalyst supports, and desiccants.
High purity and tunable surface area
Excellent thermal and chemical stability
Low cost compared to other silica-based materials
Environmentally friendly production process
