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 hot factory supply microsilica fumed silica silica fume

Our hot manufacturing facility materials microsilica, also known as fumed silica or silica fume. This product is an extremely fine powder. It originates from the production of silicon steel or ferrosilicon alloys. We produce it under rigorous quality assurance.

The major chemical part is silicon dioxide (SiO2). Our microsilica usually has a minimum SiO2 web content of 85%. Greater grades get to over 90% and even 95%. Various other components like carbon, moisture, and trace oxides are present in percentages. We keep these low. Reduced contamination degrees are very important for performance.

The physical residential or commercial properties are key. The fragments are extremely tiny. Ordinary particle size is normally listed below 1 micron. This provides it a huge area. Area often measures in between 15 and 30 square meters per gram. This high area makes the product highly reactive. The powder looks grey or white. Its bulk density is fairly low. It is extremely light-weight and flows like a liquid.

We offer various grades. These grades vary in SiO2 pureness and specific surface. We can tailor requirements to meet specific customer demands. Our standard product packaging is 25kg bags. These are multi-ply kraft paper bags with inner liners. We likewise provide bulk bags for bigger orders. Correct product packaging prevents moisture absorption and maintains the powder dry.

This microsilica is a powerful pozzolan. It responds strongly with calcium hydroxide in concrete. Including it to concrete mixes significantly boosts toughness. It improves longevity too. Concrete becomes more immune to chemical attack. It minimizes leaks in the structure. This makes frameworks last much longer. It is likewise made use of in refractories, ceramics, and various other specialized applications. Performance depends heavily on regular high quality. Our factory ensures trustworthy supply. We maintain limited specifications batch after batch. This uniformity is important for industrial customers.

Applications of hot factory supply microsilica fumed silica silica fume

Manufacturing facilities supply microsilica fume, additionally called silica fume. This powder is very fine. It comes from making silicon steel or ferrosilicon alloys. It’s mainly pure silica. Building contractors and makers use it widely.

Concrete gets much better with microsilica. Adding it fills tiny voids in the mix. This makes the concrete denser. Water can’t soak in as quickly. Chemicals damage it much less. The concrete gets much more powerful. It lasts much longer. This matters for big frameworks like bridges, dams, and buildings near the sea. It stops steel inside from rusting as well quick. Home builders additionally use it for strong floors and repair work jobs.

Refractory makers need microsilica too. It helps make heat-resistant linings for heaters and kilns. Including it makes the cellular linings tougher. They handle extreme warmth better. They withstand use from warm products moving. This makes heaters last longer between repair services.

Ceramic producers locate it helpful. Mixing microsilica into clays enhances the final product. The ceramics become harder. They stand up to heat shock much better. This indicates less splits when home heating or cooling quickly. It’s good for ceramic tiles, technological ceramics, and kiln furnishings.

Chemical firms utilize microsilica. Its little size and high surface assistance in lots of processes. It serves as a thickener in paints, finishes, and adhesives. It makes them stream right. It helps powders flow freely without clumping. It reinforces rubber and plastic parts, making them harder. It even works in unique cement blends for oil wells.

5 FAQs of hot factory supply microsilica fumed silica silica fume

People ask about microsilica often. Microsilica is also called silica fume or fumed silica. It is a very fine powder. Factories make it during silicon metal production.

What exactly is microsilica? It’s mostly silicon dioxide. The particles are extremely small. This powder looks like smoke. That’s why some people call it silica fume.

Why use microsilica in concrete? Adding microsilica makes concrete much stronger. It fills tiny spaces between cement grains. This creates a denser material. The concrete resists water penetration better. It also lasts longer against harsh chemicals.

What are the main benefits? The biggest plus is increased strength and durability. Structures need less repair over time. It saves money long-term. Builders use it for bridges, tunnels, and marine projects. These places need tough concrete.

Is microsilica safe to handle? You must be careful. The powder is very fine. It can float in the air easily. Workers need proper masks. Good ventilation is essential. Gloves protect the skin. Follow safety sheets always.

How do I choose good microsilica? Look for reliable factories. Consistent quality matters. Check the silicon dioxide content. High purity is best. Verify the particle size distribution. Ask for test reports. Good suppliers provide this data.
