Description
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.

Ultrafine Silica Powder– High-Purity Efficiency for Demanding Applications
Readily Available Mesh Sizes: 400, 600, and 800
Our ultrafine silica powder delivers constant quality across three precision qualities: 400 mesh , 600 mesh , and 800 mesh . Each grade is very carefully refined to fulfill rigorous particle dimension requirements. The finer the mesh number, the smaller the fragments– 800 mesh provides the highest possible excellence for applications requiring maximum surface area and sensitivity.
This product is made from high-purity quartz or amorphous silica sources. It consists of very little impurities, guaranteeing trusted efficiency in sensitive commercial processes. The powder appears as a free-flowing white product with excellent dispersibility in water-based and polymer systems.
Silica Fume/ Microsilica– Engineered for Strength and Durability
In addition to basic mesh grades, we supply silica fume (also referred to as microsilica ). This ultrafine by-product of silicon and ferrosilicon manufacturing includes spherical particles a lot smaller than cement grains. Its typical fragment size is about 0.1 to 0.2 micrometers– roughly 100 times finer than average cement.
Silica fume dramatically boosts concrete strength, lowers permeability, and boosts resistance to chloride and sulfate assault. Building contractors and designers utilize it in high-performance concrete, precast components, and aquatic frameworks where long-term sturdiness matters.
All our silica items undergo extensive quality control. We check for chemical make-up, bit dimension distribution, dampness web content, and loss on ignition. Batch-to-batch uniformity is guaranteed, so you get the exact same efficiency whenever.
Product packaging choices consist of 25 kg multi-wall paper bags, mass big bags (1,000 kg), or custom-made remedies based on your needs. Storage needs to be in a dry, covered location to stop moisture absorption.
Whether you require fine silica powder for layers, adhesives, rubber, or microsilica for sophisticated concrete blends, our materials sustain remarkable end-product performance with reputable supply and technical support.

Applications of Ultrafine Silica Powder
Construction and Concrete Improvement
Ultrafine silica powder (readily available in 400 mesh, 600 mesh, and 800 mesh grades) plays a crucial function in contemporary building. When added to concrete, it fills small gaps between cement bits. This makes the mix denser and stronger. Home builders use it to produce high-performance concrete that withstands water, chemicals, and put on. It also lowers splitting and boosts long-lasting resilience.
Refractory Materials
In high-temperature atmospheres like furnaces and kilns, microsilica boosts the performance of refractory castables. It boosts bonding at low temperatures and boosts strength after firing. The great particles aid create secure ceramic bonds, which prolong the service life of cellular linings and decrease maintenance costs.
Ceramics and Glazes
Potters and ceramic manufacturers depend on ultrafine silica to regulate shrinking and boost thermal shock resistance. In lusters, it works as a glass former, assisting achieve smooth, also surface areas. The finer the mesh– such as 800 mesh– the extra consistent the end product shows up.
Coatings and Sealants
Paints, sealers, and commercial finishes commonly consist of silica fume to improve structure and security. It avoids pigment settling and adds density without affecting circulation. This leads to much easier application and much better surface area protection.
Various Other Industrial Uses
Silica fume likewise finds use in rubber compounding, where it reinforces tires and industrial belts. In adhesives, it manages thickness and avoids drooping. Some specialized plastics use it to enhance solidity and heat resistance. Each mesh dimension serves various requirements– coarser grades for mass dental filling, finer ones for precision applications.

5 FAQs of Ultrafine silica powder 400 mesh 600 mesh 800 mesh silica fume Microsilica
Frequently Asked Questions About Ultrafine Silica Powder
What is ultrafine silica powder?
Ultrafine silica powder is a very fine form of silicon dioxide. It comes in different mesh sizes like 400, 600, and 800 mesh. The higher the mesh number, the finer the particles. This powder is also known as microsilica or silica fume. It is used to improve strength and durability in construction materials.
How does mesh size affect performance?
Mesh size shows how fine the powder is. A 400 mesh powder has larger particles than 800 mesh. Finer powders like 800 mesh fill small gaps better. They also react faster in cement mixtures. This leads to stronger and denser concrete. Choose the mesh size based on your project needs.
What are the main uses of this material?
This powder is mainly used in high-performance concrete, grouts, and mortars. It helps reduce water use while increasing strength. It also blocks harmful substances from entering concrete. That makes structures last longer. Some industries use it in ceramics, paints, and rubber too.
Is silica fume the same as ultrafine silica powder?
Yes, silica fume and ultrafine silica powder refer to the same material. Both names describe very fine amorphous silica. It is a byproduct of silicon metal production. The terms are often used interchangeably in construction and manufacturing.
How should I store ultrafine silica powder?
Keep the powder in a dry, sealed container. Moisture can cause clumping and reduce effectiveness. Store it away from direct sunlight and heat sources. Use clean tools when handling to avoid contamination. Proper storage ensures consistent performance in your mix.
