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 buy nano micro production sio2 silica fume microsilica a200 raw material 92% powder 85%25 90%25 95u per kg

Here’s the product information about nano micro silica fume A200. This is raw material silica fume powder. It is known as microsilica. The grade is A200. It contains a high amount of silicon dioxide. The SiO2 content is 92% minimum. This makes it very pure. The powder has different bulk densities available. You can get it at 85%, 90%, or 95% packed density. The particle size is fine. It measures about 95 microns per kilogram. This fineness helps it work better in mixes.

Silica fume comes from producing silicon metal or ferrosilicon alloys. It is a by-product. The process captures the fine particles. Then it is collected and processed. The result is this ultra-fine powder. This powder is reactive. It works well with cement and other binders. Adding it to concrete improves the concrete. It makes concrete much stronger. It also makes concrete more durable. The concrete gets denser. Water finds it harder to penetrate. This reduces damage from chemicals. It also reduces damage from freeze-thaw cycles. Structures last longer.

Builders and engineers use this material. It goes into high-performance concrete. It is good for bridges. It is good for tunnels. It is good for marine structures. Refractory producers also use it. It improves fire-resistant products. Ceramic manufacturers find it useful. It enhances their products too. The A200 grade meets common industry standards. It is reliable for demanding jobs. It ensures quality in the final application. Using this silica fume gives better results. It optimizes material performance. Consider it for projects needing top strength and longevity.

Applications of buy nano micro production sio2 silica fume microsilica a200 raw material 92% powder 85%25 90%25 95u per kg

Silica fume microsilica, often called A200, is a very fine powder. It contains mostly silicon dioxide. The purity level is high, around 92%. It is available in different grades: 85%, 90%, and 95%. This material is sold by the kilogram. Builders and manufacturers use it widely. Its tiny particle size makes it valuable.

One major use is in concrete. Adding silica fume improves concrete strength greatly. It makes concrete much more durable. The concrete becomes much harder to penetrate by water or chemicals. This protects the steel reinforcement inside from rusting. Structures like bridges and marine docks last much longer because of it.

Refractory producers also depend on this powder. Refractories are materials that resist extreme heat. Silica fume helps make these materials stronger. It helps them last longer in furnaces and kilns. The material bonds better when silica fume is present. This leads to better performance under high temperatures.

The ceramics industry uses it too. Silica fume improves the quality of ceramic products. It helps create a smoother surface finish. Ceramics become denser and stronger. This is important for tiles, sanitaryware, and technical ceramics. The fine particles fill gaps effectively.

Chemical companies find applications for it. It acts as a thickening agent. It helps control the flow properties of liquids. Products like paints, adhesives, and sealants benefit. It makes them easier to apply or gives them better stability. Its reactivity is useful in some chemical processes.

Silica fume microsilica powder is a versatile raw material. Its small size and high silica content provide unique benefits. Different industries rely on its properties. It enhances material performance in demanding environments. It is a key ingredient for high-quality construction and industrial products.
