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 Industrial Grade Silica Fume Microsilica High Purity 85% 92% 94% Oxide Powder for Cement 69012-64-2 CAS for Coating Application

Industrial grade silica fume microsilica delivers high performance. It’s a superfine powder. You get three purity levels: 85%, 92%, and 94%. This matches CAS number 69012-64-2. The powder is mainly silicon dioxide. This is key for many industrial uses. It works very well in cement and concrete. Adding microsilica makes concrete stronger and denser. It fills tiny gaps between cement particles. This reduces permeability significantly. Your concrete lasts longer. It resists water and chemicals better. Steel reinforcement gets more protection too.

The powder is vital for high-performance coatings. It improves the coating’s physical properties. Abrasion resistance increases. Durability improves against harsh weather. The fine particles create a tighter film. This barrier shields surfaces effectively. Microsilica also helps control viscosity. It prevents sagging during application. You get a smoother finish. This is important for protective paints and industrial finishes.

Refractory applications benefit greatly. Microsilica enhances high-temperature strength. It improves thermal shock resistance. Foundry castings become more durable. Investment casting molds gain better surface finish. Oil well cementing operations rely on it. The powder plugs micro-fractures efficiently. This improves wellbore integrity under pressure.

The powder is very fine. Handle it carefully to avoid dust. Use proper ventilation. Wear a dust mask and gloves. Store it in a cool, dry place. Keep containers tightly sealed. This prevents moisture absorption and caking. Industrial grade silica fume microsilica is a versatile material. Its high purity grades offer specific advantages. Choose the right purity for your cement project or coating application.

Applications of Industrial Grade Silica Fume Microsilica High Purity 85% 92% 94% Oxide Powder for Cement 69012-64-2 CAS for Coating Application

Industrial grade silica fume microsilica is a very fine powder. It’s mostly silicon dioxide (SiO2). This material comes from making silicon metal or ferrosilicon. The powder particles are incredibly small. This small size gives it special properties useful in coatings.

Adding silica fume to cement-based coatings improves them significantly. It makes the coating much denser. The tiny particles fill the smallest gaps between cement grains. This stops water and chemicals from moving through the coating easily. The coating becomes almost waterproof. This protects the surface underneath much better.

The coating also gets much harder and stronger. Silica fume reacts with cement. This reaction creates extra strong bonds inside the coating. The surface resists wear and abrasion much longer. It won’t chip or dust easily. The coating becomes more durable against physical damage.

Chemical resistance improves too. Aggressive substances like acids, salts, or chlorides struggle to penetrate the dense structure. This protects concrete and steel reinforcement from corrosion. It’s vital for structures exposed to seawater, deicing salts, or industrial chemicals.

We offer high purity grades: 85%, 92%, and 94% SiO2. Higher purity generally means better performance. The ultra-fine powder mixes well into coatings. It can make the mixture slightly thicker. Adjusting the mix design compensates for this. Proper dispersion is key to getting all the benefits. Use appropriate mixers. Always follow the supplier’s guidelines for best results. Silica fume powder is safe when handled correctly. Wear a dust mask to avoid breathing it in.
