What is aerogel powder? Aerogel is a solid material with the smallest density in the world. The common aerogel is silicon gel, first made by American scientist Kistler in 1931 for gambling with his friends. Many kinds of aerogels exist, including silicon, carbon, sulfur, metal oxide, etc. Aerogel is a compound word. Here aero is an adjective meaning "in the air." The gel is gel. It means gel of air. The gel of any substance can be called aerogel as long as it can be dried to remove the internal solvent and keep its shape unchanged, and the product has high porosity and low density.
Aerogel powder is used as thermal insulation material Due to its low sound speed, silicon aerogel is an ideal acoustic delay or high-temperature sound insulation material. The acoustic impedance of this material has a large variable range (103-107 kg/m2 · s). It is an ideal acoustic impedance coupling material for ultrasonic detectors, such as the common acoustic impedance turn Zp=1.5 × L07 kg/m2 · s piezoelectric ceramic is used as an ultrasonic generator and detector. At the same time, the good resistance of air is only 400 kg/m2 · s. Using silicon aerogel with a thickness of 1/4 wavelength as the acoustic resistance coupling material between piezoelectric ceramics and air can improve the transmission efficiency of sound waves and reduce the signal-to-noise ratio in device applications. The preliminary experimental results show that the silicon aerogel with a density of about 300 kg/m3 as the coupling material can increase the sound intensity by 30 dB. A higher sound intensity gain can be expected if the silicon aerogel with a density gradient is used.
Aerogel powder in energy storage devices In the research on the quantum size effect of materials. Due to the formation of quantum dot structure in the nano network of silicon aerogel, the results of chemical vapor infiltration doping Si and solution doping C60 show that the dopant exists in the form of nanograins, and strong visible light emission is observed, which provides strong evidence for the quantum confinement effect of porous silicon. Using the structure of silicon aerogel and the nonlinear optical effect of C60, a new type of laser protective glasses can be further developed. Doping is also an effective way to form nanocomposite materials. In addition, silicon aerogel is a material with an adjustable refractive index. Using aerogel media with different densities as Cherenkov threshold detectors, the mass, and energy of high-energy particles can be determined. Because high-speed particles can easily penetrate porous materials and gradually decelerate, a "soft landing" can be achieved. For example, transparent aerogel is selected to capture high-speed particles in space, and blocked and trapped particles can be observed with the naked eye or microscope.
