Why aerogel powder has thixotropic effect
What is Aerogel Powder?Aerogel, also known as wet gel or hydrogel, is a porous material that can be made by replacing the liquid within the gel with air. KNFW silica Aerogel Powder is a low density aerogel with low thermal conductivity and a high specific surface area. High surface activity and purity. Widely used for building insulation, industrial insulating materials, polymer material, aerospace.
Characteristics and uses of aerogel powder
Aerogel's ultra-lightweight, translucent color is often referred to as "solid smoke" and "frozen smoke". This material may look fragile, but is durable and strong. It can even withstand high temperatures of up to 1,400°F. Aerogels' properties have many uses in space exploration. Aerogels are used in the Russian "Peace," and American "Mars Pathfinder," spacecraft. Guinness World Records listed a NASA-developed aerogel that has a density of just 3 mg per cubic cm as the "lowest solid density in the world".
Aerogel powder: preparation method
In most cases, the preparation of aerogels involves a sol gel process and a supercritical drying procedure. By controlling the conditions for the polycondensation and hydrolysis reactions, sol-gel produces nanoclusters of different structure in the solution. These clusters then adhere to one another to form a solid gel. The solid skeleton is filled with liquids after the chemical reaction. Supercritical drying is used on gel to avoid damage to its material structure due to surface tension. The gel is put in a pressure vessel, which increases temperature and pressure to transform the liquid gel into supercritical fluid. The interface between the liquid and gas disappears. Also, surface tension is no longer present. The pressure vessel then releases the supercritical fluid, producing a low-density, porous and disordered material.
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.
