Recently, in-depth research has introduced inorganic aerogels, cutting-edge three-dimensional nanoporous materials known as "solidified smoke". With a porosity of over 90%, they feature ultra-low thermal conductivity, low density and large specific surface area, standing out as high-efficiency thermal insulation materials. Three typical types of inorganic aerogels have been widely studied. Silica aerogels perform well at medium and low temperatures, featuring fire resistance and waterproofness, and are applied in building thermal insulation and new energy vehicles. Alumina aerogels boast excellent high-temperature stability and can maintain stable performance above 1000°C, ideal for high-temperature industry and aerospace equipment. Aluminosilicate composite aerogels solve the brittleness defect of traditional products, with heat resistance up to 1400°C, suitable for missiles and aero-engines. Researchers are optimizing preparation techniques to reduce costs and eliminate impurities. As technology matures, inorganic aerogels will achieve large-scale industrial application, supporting energy conservation and technological progress across multiple industries. https://www.tiktok.com/@mia_iota/video/7597717976720149782
