What is aerogel powder? Aerogel is a light porous solid material obtained by replacing the liquid inside the gel with air without changing the volume of the hydrogel (wet gel). KNF-W silica aerogel powder is an aerogel material with low density, low thermal conductivity, high specific surface area and high adsorption prepared by atmospheric drying method. High purity, high surface activity, widely used in building insulation, industrial insulation, polymer materials, aerospace.
Characteristics of aerogel powder Aerogel is sometimes called "solid smoke" or "frozen smoke" because of its translucent color and ultra-lightweight. This new material looks fragile, but it is strong and durable and can withstand a high temperature of up to 1400 ℃. These characteristics of aerogels have many applications in space exploration. Aerogel materials are used on the Russian "Peace" space station and the American "Mars Pathfinder" spacecraft. A new type of aerogel developed by NASA was once listed in the Guinness World Records as the "lowest density solid in the world" because its density is only 3 mg per cubic centimeter.
Preparation method of aerogel powder The preparation of aerogels usually consists of a sol-gel process and supercritical drying treatment. In the process of sol-gel, by controlling the solution's hydrolysis and polycondensation reaction conditions, nanoclusters with different structures are formed in the solution, and the clusters adhere to each other to form a gel. In contrast, the solid skeleton of the gel is filled with liquid reagents left after the chemical reaction. To prevent damage to the material structure caused by the surface tension in the micropore during the drying process of gel, the supercritical drying process is used to treat the gel. The gel is placed in a pressure vessel to increase the temperature and pressure so that the liquid in the gel changes into a supercritical fluid. The gas-liquid interface disappears, and the surface tension no longer exists. The pressure vessel releases the supercritical fluid to obtain porous, disordered Low, density aerogel material with a nanometer-scale continuous network structure.
Price of aerogel powder Aerogel powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of aerogel powder. A large amount of large amount will be lower. The Price of aerogel powder can be found on our company's official website.
