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 Factory high whiteness silica fume for ceramics silicon dioxide

Here’s the product content for high whiteness silica fume for ceramics. It uses simple language, avoids complex words, and cuts transition words. The text flows logically. It ends with the final specification point.

This silica fume is for ceramics. It is very white. It makes ceramic products look bright. Our factory makes it. We control the whiteness tightly. You get consistent results. The whiteness level is high. It measures 96% minimum. This is tested with a standard reflectance meter. The material is fine powder. It is mostly silicon dioxide. SiO2 content is over 99%. This purity matters. It ensures strong performance. The particles are very small. We control the particle size carefully. Fine particles fill gaps well. This reduces porosity in your ceramics. It makes the final product stronger. Density is low. It is about 150-200 kg/m3 loose bulk density. This makes it easy to handle. It mixes smoothly into ceramic slips or bodies. Moisture content is very low. It is below 1.0%. This prevents clumping. Storage is simple. Keep it dry. It comes packed in moisture-proof bags. Use it in glazes. Use it in bodies. It acts as a flux. It helps vitrification. This means melting happens better. Firing temperatures might be lower. This saves energy. Color development improves. Your whites stay white. Your colors stay bright. Iron contamination is minimal. Iron oxide is under 0.1%. This protects the whiteness. Alkali content is low too. This prevents unwanted reactions. The silica fume is amorphous. It is not crystalline. It reacts fast during firing. This improves efficiency. Performance is reliable. It works in many ceramic applications. Tiles benefit. Sanitaryware benefits. Tableware benefits. Technical ceramics benefit. It enhances strength. It improves surface finish. It helps achieve the desired whiteness.

Applications of Factory high whiteness silica fume for ceramics silicon dioxide

Factory high whiteness silica fume is a special powder. It is very fine. It contains a lot of silicon dioxide. Ceramic makers use it to improve their products. This silica fume makes ceramics stronger and harder. It fills tiny spaces between other particles. This makes the ceramic body denser. A denser body means less water absorption. Products resist stains and damage better.

This material also improves the whiteness of ceramics. It has very low iron content. Iron can cause yellow or brown colors. Low iron means brighter whites and cleaner colors. This is vital for high-quality tiles and sanitaryware. Customers expect pure white surfaces. This silica fume helps achieve that.

The fine particles help during firing. They promote better sintering. Sintering bonds particles together under heat. Better sintering means a tougher final product. It also reduces firing shrinkage. Consistent size after firing is important. This saves material and reduces waste.

Glaze performance also benefits. Adding this silica fume to glazes improves how they melt. It creates smoother, glossier finishes. The glaze sticks to the ceramic body better. This reduces defects like crawling or pinholes. The final look is more professional.

Sanitaryware manufacturers rely on it. Items like sinks and toilets need high strength and stain resistance. They also need a bright white appearance. This silica fume delivers these properties. Technical ceramics use it too. These ceramics need extreme durability and precise properties. The silica fume helps meet demanding specifications. It is a key ingredient for premium ceramics.

5 FAQs of Factory high whiteness silica fume for ceramics silicon dioxide

What is factory high whiteness silica fume for ceramics? It’s a very fine powder. It’s mostly silicon dioxide (SiO2). Factories collect it as a by-product. It comes from making silicon metal or ferrosilicon alloys. Its particles are extremely small. This powder is very white. It has very high purity. Ceramic makers use it to improve their products.

Why is whiteness so important? Pure white ceramics need pure white materials. Standard silica fume often has a grey color. Grey silica fume makes white ceramics look dirty. It gives them a dull, off-white look. High whiteness silica fume avoids this problem. It lets makers create bright, clean white ceramics. This matters for high-value products like tiles or sanitaryware.

How does it improve ceramic properties? The tiny particles fill gaps. They make the ceramic body denser. This reduces porosity. Less porosity means the ceramic is stronger. It becomes more durable. The surface finish gets smoother. High purity silica fume also helps control firing. It makes the final product more reliable. It makes ceramics stronger.

Is it safe to handle? Yes, but treat it like any fine powder. Avoid breathing the dust. Wear a dust mask. Use gloves. Keep the area ventilated. Store it in a dry place. Keep the bag sealed. Follow normal safety rules for powders. It’s non-toxic. Handle it carefully.

How do you use it in ceramics? Mix it thoroughly into your ceramic batch. Add it during the raw material blending stage. Ensure even distribution. The small size helps it blend well. Use the amount recommended for your recipe. Test small batches first. It integrates smoothly with other powders like clay or feldspar.
