Why does aerogel powder have gel properties
What is Aerogel Powder?Aerogel has the smallest density of any solid material in the world. The density is set at 3 kg/m3. Kistler and his friends first created the silicon gel aerogel in 1931. Aerogels come in many forms, such as silicon, carbon or sulfur. Aerogel is actually a compound. Aero is an adjective that means "in air". A gel is a gel. It means air gel. This is the term for aerogel.
Aerogel powder as thermal insulation material
The fine network structure of aerogel silicon effectively limits the spread of local thermal excitement, and its thermal conductivity solid is 2-3 orders lower than glassy materials. The nano-pores in silicon aerogel inhibit gas molecules from contributing to heat conduction. The refractive indices of silicon aerogel are close to 1 and the ratio of annihilation coefficients of infrared versus visible light is greater than 100. It can pass through sunlight, and stop the infrared radiation from the ambient temperature. It is an ideal transparent thermal insulating material, and it has been applied to solar energy utilization and energy conservation in buildings. The radiant heat conduction in silicon aerogel is further reduced by doping. Thermal conductivity can be as low at 0.013w/m*K for aerogels doped with carbon, when room temperature and pressure are normal. This is the solid with the lowest thermal resistance and it is expected to replace polyurethane as a refrigerator insulation material. Silica Aerogel can become a high temperature thermal insulation material by adding titanium dioxide. Thermal conductivity of 800K is just 0.03w/m*K. This material will be further developed to support military products.
Aerogel powder in energy storage devices
The carbon aerogel is created by sintering the organic aerogel gel. This porous carbon material has been developed as a replacement for fibrous carbon. The material has a large specific area (600-1000m2/g) as well as a high level of conductivity (10-25s/cm). Moreover, the density of this material varies from 0.05 to 1.0 g/cm3. Imagine an appropriate electrolyte has been poured into the micropores. A new rechargeable lithium-ion battery could be created. It would have excellent properties such as high storage capacity and low internal resistance. It is also lightweight and has strong charging and discharge ability. The preliminary experimental findings show that the carbon aerogel's charging capacity reaches 3x104/kg2, its power density is 7kW/kg, while the performance of repeated charging/discharging is excellent.
Prices of aerogel powder
Aergel powder's price is affected by its particle size and purity. Its volume of purchase can also influence the price. The price of a large quantity will be lower. On our official website, you can find the price of Aerogel Powder.
