Overview of Fumed Silica

Fumed silica, also known as pyrogenic silica, is an ultra-fine, high-purity amorphous silicon dioxide (SiO2) produced via the combustion of silicon tetrachloride in an oxygen-hydrogen flame. It appears as a fluffy white powder and is valued for its ability to thicken, stabilize, and reinforce materials.

Features of Fumed Silica

• High Surface Area: Typically ranges from 50 to 380 m²/g, providing excellent thickening and reinforcing properties.
• Hydrophilic or Hydrophobic Variants: Available in both forms depending on surface treatment, allowing for tailored applications.
• Excellent Thixotropy: Increases viscosity and improves flow properties of liquids and pastes.
• Chemical Inertness: Resistant to most chemicals, making it suitable for a wide range of industrial uses.

•  Enhances free-flowing properties and stability.

Specification of CAS 14808-60-7 FUMED SILICA Precipitated Silica Pure Sio2 Silicon Dioxide

CAS 14808-60-7 fumed silica is a fine white powder made of silicon dioxide. It is produced by burning silicon tetrachloride in a hydrogen-oxygen flame. This method creates tiny particles with high purity. The product has a high surface area. This makes it useful for thickening, reinforcing, and stabilizing materials. It is different from precipitated silica. Fumed silica has lower moisture content. It also has better dispersibility in organic systems.

The main component is SiO2. The purity is over 99.8%. The surface area ranges from 200 to 400 m²/g. The particle size is between 5 and 50 nanometers. The pH value is around 3.7 to 4.3. The bulk density is low, typically 30-60 g/L. It is hydrophobic. This allows it to mix well with non-polar substances. It does not dissolve in water or most solvents. It stays stable under high temperatures. It can handle temperatures up to 1,000°C without breaking down.

This silica is used in many industries. In coatings and paints, it prevents sagging. It improves texture. In adhesives, it controls flow. It adds strength. In plastics, it increases hardness. It reduces shrinkage. In cosmetics, it thickens creams. It prevents clumping. In pharmaceuticals, it acts as a carrier. It helps tablets hold their shape.

Safety is important. The powder is non-toxic. It is safe for skin contact. Inhalation should be avoided. Dust can irritate lungs. Protective gear like masks and gloves is recommended. Storage requires a dry, cool place. Keep containers sealed. Moisture causes clumping. Direct sunlight or high heat should be avoided.

Fumed silica works well with other materials. It boosts performance in rubber products. It enhances durability in silicone sealants. It improves print quality in inks. The product meets industry standards for quality. Testing includes checks for purity, particle size, and moisture. Batch numbers ensure traceability. Custom grades are available. Adjustments in surface treatment or particle size can be made for specific needs.

Applications of CAS 14808-60-7 FUMED SILICA Precipitated Silica Pure Sio2 Silicon Dioxide

CAS 14808-60-7 fumed silica, also called precipitated silica or pure SiO2 silicon dioxide, is a versatile material used in many industries. It is made through high-temperature processes or chemical precipitation, resulting in fine particles with high surface area. This makes it useful for improving product performance.

In rubber products like tires and seals, fumed silica acts as a reinforcing agent. It strengthens the material, boosts wear resistance, and helps reduce rolling resistance in tires. This improves fuel efficiency in vehicles. The fine particles fill gaps in rubber compounds, enhancing durability.

Coatings and paints use fumed silica as a thickening agent. It prevents sagging or dripping during application. The material controls flow behavior, ensuring even coverage on surfaces. It also improves scratch resistance in finished coatings.

In adhesives and sealants, fumed silica adjusts viscosity. It prevents settling of solid components in liquid formulations. This ensures consistent performance during use. The material also enhances bonding strength in adhesives.

Pharmaceuticals and cosmetics rely on fumed silica for its ability to absorb liquids. It acts as a carrier for active ingredients in tablets or powders. In cosmetics, it improves texture and prevents clumping in products like powders or creams.

Food-grade fumed silica serves as an anti-caking agent. It keeps powdered foods like spices or drink mixes free-flowing. The material absorbs moisture, extending shelf life without affecting taste or safety.

Industrial applications include use in plastics and gels. Fumed silica improves the mechanical properties of plastics, such as stiffness and heat resistance. In gels, it stabilizes structure and prevents separation.

The material’s high purity and chemical inertness make it safe for sensitive applications. It does not react with other substances, ensuring stability in final products. Its small particle size allows even distribution in mixtures.

Fumed silica is available in different grades to meet specific needs. Modifications can adjust surface properties for better compatibility with various matrices. This flexibility supports its use in diverse fields.

Handling requires care to avoid inhalation of fine particles. Proper safety measures, like using masks and ventilation, are essential during processing.

5 FAQs of CAS 14808-60-7 FUMED SILICA Precipitated Silica Pure Sio2 Silicon Dioxide

CAS 14808-60-7 fumed silica is a fine white powder. It is made by burning silicon tetrachloride in a hydrogen-oxygen flame. This process creates tiny particles of silicon dioxide. The particles have high purity and a large surface area. They are widely used in industries like coatings, adhesives, and pharmaceuticals. Below are answers to common questions about this product.

What is fumed silica? Fumed silica is a synthetic form of silicon dioxide. It is produced through a vapor-phase process. The result is a lightweight powder with strong thickening and reinforcing properties. It is different from crystalline silica. It does not pose the same health risks when handled properly. Its main role is to improve product performance in various applications.

How does fumed silica differ from precipitated silica? The production method sets them apart. Fumed silica uses high-temperature flame hydrolysis. Precipitated silica is made by reacting sodium silicate with acid in liquid. Fumed silica has higher purity and smaller particle size. This gives it better performance in applications needing high strength or transparency.

What are the key uses of fumed silica? It acts as a thickener in paints and coatings. It prevents settling in liquids. It reinforces rubber products like tires. In cosmetics, it controls viscosity. In food, it stops powders from clumping. Its ability to absorb moisture makes it useful in pharmaceuticals for stabilizing tablets.

Is fumed silica safe to handle? Proper safety measures are essential. Wear gloves and masks to avoid skin contact or inhaling dust. It is non-toxic but can cause irritation. Follow workplace guidelines for dust control. Keep it away from eyes and lungs. Always check safety data sheets for specific handling instructions.

How should fumed silica be stored? Store it in a dry, cool place. Keep containers tightly sealed. Moisture causes clumping. Avoid exposure to high humidity. Use original packaging or airtight containers. Shelf life is long if storage conditions are stable. Check for lumps before use. Break them gently if they form.
