Specification of Silica Aerogel Powder and Particles
Requirements of Silica Aerogel Powder and Particles
Silica aerogel powder and particles are ultra-lightweight materials known for their remarkable thermal insulation residential or commercial properties. They are made from silica gel that has been dried using a special process to eliminate fluid without diminishing the structure. This results in a product that mores than 90% air yet maintains strong architectural integrity at the microscopic degree.
Physical Properties
The typical bulk density of silica aerogel powder varies from 30 to 150 kg/m FOUR . Particle dimension can vary based on client needs, commonly dropping between 1 to 100 micrometers . The product appears as a fine, white or beige powder with a cosy texture. It really feels dry to the touch and flows easily, similar to talcum powder.
Thermal Performance
Silica aerogel reveals extremely low thermal conductivity– generally in between 0.013 and 0.020 W/(m · K) at room temperature. This makes it among the best strong insulators offered. Its performance stays stable throughout a vast temperature level variety, from — 200 ° C to +650 ° C , depending upon the details grade.
Chemical Structure
The main component is amorphous silica (SiO TWO), with purity levels frequently going beyond 95%. Trace quantities of wetness or processing help may exist however do not influence efficiency. The product is non-toxic, non-flammable, and chemically inert under regular conditions.
Handling and Storage
Shop silica aerogel powder in a completely dry, closed container far from wetness. Though secure to take care of, users should put on typical safety gear like handwear covers and a dirt mask to prevent breathing of great fragments. Avoid prolonged skin get in touch with to avoid light irritation.
This product suits applications in structure insulation, commercial piping, aerospace parts, and specialized finishings where marginal weight and optimum insulation are important.
Applications of Silica Aerogel Powder and Particles
Applications of Silica Aerogel Powder and Particles
Thermal Insulation
Silica aerogel powder is commonly utilized for thermal insulation. It has very reduced thermal conductivity. This makes it optimal for keeping warm in or out. Builders blend it right into plasters, renders, and protecting panels. It helps reduce power usage in homes and offices. Industrial pipelines and containers likewise use this product to reduce warm loss.
Coatings and Paints
Producers include silica aerogel particles to paints and finishes. These additives improve insulation without including much weight. The outcome is a thinner layer that still obstructs warmth well. Such finishes prevail on roof coverings, walls, and even outside equipment. They aid preserve comfy temperature levels year-round.
Personal Protective Equipment
Firemens and workers in extreme environments use gear with silica aerogel. The powder traps air in little pores. This framework reduces warmth transfer. Consequently, protective clothing stays lightweight but provides strong thermal resistance. Gloves, boots, and fits all benefit from this technology.
Aerospace and Automotive
In aerospace, every gram matters. Silica aerogel powder supplies high-level insulation with nearly no weight. Satellites, room matches, and aircraft components utilize it to manage temperature level swings in space or at high elevations. In autos, it enters into battery packs for electrical lorries. It keeps batteries risk-free by reducing warmth spread throughout faults.
Consumer Goods
You can locate silica aerogel in day-to-day things too. Outdoor coats, sleeping bags, and also footwear use it for warmth without bulk. Sports devices like ski boots or bike frameworks may include aerogel layers. These products stay light while providing much better convenience in winter.
Specialty Product packaging
High-value or temperature-sensitive goods require steady conditions during delivery. Product packaging with silica aerogel particles helps keep inner temperature levels. This is useful for medical supplies, food, and electronic devices. The product guarantees contents remain secure over cross countries.

5 FAQs of Silica Aerogel Powder and Particles
Frequently Asked Questions About Silica Aerogel Powder and Particles
What is silica aerogel powder?
Silica aerogel powder is a lightweight material made from silica gel. It has a very porous structure. This gives it excellent thermal insulation properties. The powder form makes it easy to mix into coatings, composites, or other materials.
Why is silica aerogel so light?
Silica aerogel is over 90% air. During production, liquid in the gel is replaced with gas. This keeps the solid framework intact while removing most of the weight. That’s why it feels almost like nothing in your hand.
Is silica aerogel safe to handle?
Yes, but you should take basic precautions. The fine particles can irritate your eyes, skin, or lungs. Always wear gloves, safety glasses, and a mask when working with the powder. Store it in a sealed container away from moisture.
How is silica aerogel used in real applications?
People add it to paints, plasters, and fabrics to improve insulation. It’s also used in aerospace, oil and gas pipelines, and protective clothing. Because it blocks heat so well, even a small amount makes a big difference in performance.
Does silica aerogel absorb water?
Standard silica aerogel is hydrophilic, which means it attracts water. This can reduce its insulating ability. However, surface-treated versions are hydrophobic. These repel water and work better in damp or outdoor environments. Always check the product type before use.
