One of the ten emerging technologies in the field of chemistry-qi ice powder
What is Aerogel Powder?Aerogel is the smallest solid in the world. Aerogels are made of silicon gel. The first was created by American scientist Kistler, in 1931, for a game with friends. Aerogels come in many forms, including silicon and carbon aerogels. Aerogel is actually a compound. Here, aero means "in air." The gel is gel. It is a gel made of air. It is possible to call any gel aerogel, as long as the gel can be dried out and its shape remains unchanged and it has high porosity.
Aerogel powder as thermal insulation material
A low sound speed makes silicon aerogel an ideal material to delay sound or for high temperature sound insulation. This material is characterized by a wide range of acoustic impedance (103-107kg/m2*s). It is an excellent acoustic coupling material for ultrasonic detections. Air has a good resistance only of 400 kg/m2* s. However, using silicon aerogel of a thickness of 1/4 of a wavelength between piezoelectric tiles and air as an acoustic resistence coupling material can improve sound wave transmission efficiency and reduce signal-to noise ratio. The preliminary experiment results indicate that silicon aerogel, with a densities of 300 kg/m3, can be used as a coupling material to increase sound intensity up to 30 dB. If the silicon aerogel has a density gradient, a higher gain in sound intensity is expected.
Aerogel powder in energy storage devices
Research on quantum size effects of materials. In the research on the quantum size effect of materials, due to the formation in nano-network of silicon aerogel of a quantum dot structure, the results from chemical vapor doping Si, and solution doping C60 reveal that the dopant is in the form nanograins. A strong visible light emitting emission has been observed. The structure of silicon aerogel combined with the nonlinear effect of C60 can be used to develop a new kind of laser protective glass. Doping is another effective way to produce nanocomposite materials. A silicon aerogel material that has an adjustable refractive indices is also available. Aerogel media can be used to detect high-energy particles by using different densities of aerogel as Cherenkov detectors. High-speed particles are able to penetrate porous material and slowly decelerate. This allows for a "soft land". The transparent aerogel used in this case can capture high-speed particle in space.
Prices of aerogel powder
Aergel powder's price is affected by its particle size, purity, and purchase volume. The price of a large quantity will be lower. On our official website, you can find the price of Aerogel Powder.
