Overview of Airgel Particles, SiO2 Silica Nano Aerogel Powder For Thermal Insulation
Aerogels are ultralight, highly porous materials known for their exceptional insulation properties, remarkable low density, and incredible strength-to-weight ratios. Often referred to as “frozen smoke” due to their ethereal appearance, aerogels are produced by replacing the liquid component of a gel with gas, typically through supercritical drying, which avoids collapse of the gel structure. Composed primarily of air (up to 99.98%), these materials exhibit a wide array of unique characteristics that make them valuable across various industries.
Features of Airgel Particles, SiO2 Silica Nano Aerogel Powder For Thermal Insulation
-
Extremely Low Density: Aerogels are some of the world’s lightest solids, with densities as low as 0.001 grams per cubic centimeter.
-
Superb Insulation: They possess extremely low thermal conductivity, making them among the best insulators known to man, effective at temperatures from -270°C to 1,000°C.
-
High Porosity: With a porous structure that can reach up to 99.9%, aerogels have an incredibly large internal surface area, enhancing their functionality in absorption and catalysis applications.
-
Translucent to Transparent: Depending on their composition, aerogels can transmit light, giving them a unique semi-transparent or transparent appearance.
-
Mechanical Strength: Despite their fragile appearance, aerogels can be engineered to possess significant mechanical strength, capable of bearing considerable weight.
-
Chemically Inert: Many aerogels are chemically stable and resistant to corrosion, making them suitable for harsh environments.

Parameters of Airgel Particles, SiO2 Silica Nano Aerogel Powder For Thermal Insulation
Airgel particles are an artificial material made of tiny water droplets that can be freeze-dried or treated to form structures that exhibit thermal insulation properties. These particles are known for their high resistance to temperature changes and their ability to adsorb heat in order to maintain a constant temperature within a device.
SiO2 is a common ingredient used in airgel-based thermal insulators because it has excellent electrical conductivity and resistance to moisture. Silica nano aerogels are another material that can be formed from SiO2 using the same process as airgel particles. These nano-airgels are often used in systems where high temperatures must be maintained due to the use of harsh cooling devices.
The size of the nano-airgels affects their thermal insulation performance. The larger the particle, the more impurities it contains, which can make it less effective at retaining heat. On the other hand, the smaller the particle, the better its thermal insulation properties can be achieved.
Overall, airgel-based thermal insulations have proven to be effective at controlling temperature within a variety of applications, including those that require long-term cold storage. As technology continues to advance, we can expect to see even greater improvements in the quality of these materials, making them a valuable addition to many industries.

FAQs of Airgel Particles, SiO2 Silica Nano Aerogel Powder For Thermal Insulation
Q: Is Airgel Particles, SiO2 Silica Nano Aerogel Powder For Thermal Insulation fragile?
A: Traditional aerogels are brittle and fragile; however, advancements have led to the development of “flexible” or “rigid” aerogels that maintain their unique properties while being more durable.
Q: How is Airgel Particles, SiO2 Silica Nano Aerogel Powder For Thermal Insulation made?
A: Airgel Particles, SiO2 Silica Nano Aerogel Powder For Thermal Insulation is synthesized by replacing the liquid in a gel with gas without causing the structure to collapse. This is typically achieved through supercritical drying, where the solvent is converted to a supercritical state, allowing it to evaporate without forming liquid-gas interfaces that could damage the gel structure.
Q: Is Airgel Particles, SiO2 Silica Nano Aerogel Powder For Thermal Insulation expensive?
A: Historically, aerogels have been costly due to their complex manufacturing process. However, with technological advancements and economies of scale, costs are gradually decreasing.
Q: Can Airgel Particles, SiO2 Silica Nano Aerogel Powder For Thermal Insulation conduct electricity?
A: Most aerogels are poor conductors of electricity due to their porous, insulating nature. However, certain metal-oxide aerogels can display semiconducting or even conducting properties.
Q: Is Airgel Particles, SiO2 Silica Nano Aerogel Powder For Thermal Insulation environmentally friendly?
A: Aerogels themselves do not pose environmental hazards, and their use in insulation can reduce energy consumption. However, the production process may involve chemicals that require careful handling and disposal.
