About Nanoparticle Silica Aerogel SiO2 Aerogel :
Aerogel This is a lightweight nanosolid material having a porous network structure and an enclosed network skeleton with large amounts of gaseous dispersion. Because of their particular structure, aerogel materials are versatile.
These are just a few of them: silica aerogel Materials are formed from the exploration of SiO2 using aerogel technology. This gel is rich in raw materials, easy to process, and can be controlled easily. It has high transparency, low thermal conductivity, as well as a high specific surface area.
Silica aerogel Because of its high surface area, porosity, and lightweight, silica aerogels will be applicable in many industries, from pharmaceutical to semiconductor. You can chemically modify Silica Aerogels to fit specific applications. Because Silica aerogel materials are uniform in their nanoparticle structure, uniform size, and pore distribution, they have excellent thermal insulation performance. Because of its low density, the solid heat conductivity is enhanced and reduced. In addition, sunscreen can also be utilized to increase your specific coefficient of extinction or to reduce the radiation heat conduction.
Silica aerogel is an amorphous material composed of silica. It contains a skeleton density of around 2200kg/m3. But, because of its porosity (pore volume in excess of 90 percent), it is extremely light (bulk density between 50 and 200kg/m3). The average pore size falls between 5-100 and 100 nm. The total density of aerogels used for construction purposes is between 70 and 150 kg/m 3. Acoustic properties can be very intriguing. Sound propagation through an aerogel depends upon the nature and the pressure of interstitial gases, their density, and texture. (Forest, 1998) However, sound velocity in silica is lower than in monolithic aerogel. Particulate aerogel reduces the velocity to 40m/s.
Silica aerogel can be used as a thermal insulation medium and is lightest. This material has long been considered to be a viable candidate for the development of superthermal insulation systems in aviation.

How is Nanoparticle Silica Aerogel SiO2 Aerogel produced?
Sol-gel method: The sol-gel method is a commonly used method for preparing silica aerogel. The method is to dissolve the silicic acid in the solvent, add an appropriate amount of acid or base as a catalyst, and constantly stir to get the sol. Then, the sol is dried to make the solvent volatilize, and finally, the silica aerogel is obtained. The advantages of this method are that the preparation process is simple and easy to control, but the preparation cycle is long, and a lot of organic solvents are needed.
Chemical vapor deposition method: It is the chemical reaction of silicon-containing compounds or elements under certain conditions to generate silica deposition on the surface of a certain substance so as to obtain silica aerogel. This method requires the use of high temperature, high pressure or catalyst, and other conditions. The equipment cost is high, but it can be large-scale production.
Supercritical drying: Supercritical drying is a method of drying a gel in a supercritical fluid. In the supercritical state, the density of the fluid is close to that of the liquid, and the diffusion coefficient is close to that of the gas, so the drying of the gel can be achieved in a short time. The silica aerogel prepared by the supercritical drying method has a higher porosity and specific surface area, but it requires high-pressure equipment and high cost.
Template method: The template method is a method of preparing silica aerogel by using a template. The method is to immerse the template with a specific pore structure into the silicon source solution, and then dry, sintering, and other treatments, and finally get silica aerogel. This method can control the pore size and porosity of silica aerogel by selecting templates with different pore sizes. Still, it requires the use of templates and is not suitable for large-scale production.

Nanoparticle Silica Aerogel siO2 Aerogel Application:
Thermal insulation: Silica aerogel has low thermal conductivity and high thermal resistance and can be used for thermal insulation materials. For example, applying silica aerogel to the exterior walls or the roof structure will improve the thermal insulation of the structure and decrease energy usage.
Adsorption: silica aerogels have a large specific surface area and pore volume and can adsorb water, organic matter, heavy metals, and other substances. For example, silica aerogel is used in water treatment, which can adsorb organic matter and heavy metal ions in water and improve water quality.
Sound insulation: Silica aerogel is porous and elastic and can be used as a sound insulation material. For example, the use of silica aerogel in highway noise barriers can reduce the impact of noise on the surrounding environment.
Solar cells: Silica aerogel can be used as a light absorber for solar cells. Due to its porosity and high specific surface area, it can also enhance the area of light absorption and increase the efficiency of conversion of solar cells.
Catalyst carrier: Silica aerogel has a high specific surface area and porosity, which can be used as a catalyst carrier. For example, silica aerogels used in vehicle exhaust catalyst support can improve the activity of the catalyst.
Advanced ceramics: silica aerogel can be used as one of the raw materials of advanced ceramics. Due to its high toughness, high strength, and high temperature resistance, it can be used to manufacture advanced ceramic products, such as engine parts, nozzles, and so on.
Biomedical: Silica aerogels are biocompatible and non-toxic and can be used in the biomedical field. For example, silica aerogels are used for drug carriers, dental restoration materials, biosensors, etc.
