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 high white fused silica fume quartz powder

High white fused silica fume quartz powder is a premium material designed for industrial applications requiring high purity and consistent performance. It is produced from high-quality quartz raw materials through electric arc furnace heating and vapor-phase condensation. The product consists primarily of silicon dioxide (SiO2), with a minimum content of 99.5%. This ensures excellent chemical stability and thermal resistance. The powder has a fine particle size distribution ranging from 5 to 25 micrometers. This uniform sizing allows for easy integration into various matrices while improving material density and strength.

The product features low impurity levels. Trace elements like iron (Fe2O3), aluminum (Al2O3), and calcium (CaO) are controlled below 0.05%. This minimizes color interference and enhances compatibility with high-end applications. The material’s whiteness exceeds 95%, measured using standard brightness testing methods. This makes it ideal for use in coatings, plastics, and ceramics where visual appeal matters.

High white fused silica fume quartz powder is chemically inert. It resists acid and alkali corrosion, ensuring long-term durability in harsh environments. The material has a low thermal expansion coefficient. This property reduces stress cracking in temperature-sensitive applications like electronic encapsulants or refractory materials.

Applications span multiple industries. In construction, it improves the mechanical properties of concrete and cement-based products. For electronics, it serves as a filler in epoxy resins and silicone rubber to enhance insulation and heat dissipation. The powder is also used in paints, adhesives, and composite materials to boost abrasion resistance and surface finish.

Packaging options include 25-kilogram woven bags or customized bulk containers. Storage recommendations emphasize keeping the product dry and away from moisture to prevent clumping. Technical specifications are verified through X-ray fluorescence (XRF) and laser particle size analysis. Quality assurance protocols comply with ISO 9001 standards. Batch testing guarantees consistency in particle size, purity, and performance. Custom grades are available to meet specific customer requirements.

The product is suitable for manufacturers prioritizing precision and reliability. It offers a balance of physical properties and cost-effectiveness. Technical support is provided to assist with material selection and application optimization.
