Technical Overview & Applications Use-case context
LUDOX AS-40 colloidal silica is a high-purity, aqueous dispersion of silica particles with a nominal diameter of 12 nanometers. The product, identified by the CAS number 7631-86-9, exhibits a high surface area and is stabilized by a negatively charged layer, which provides electrostatic repulsion between particles and prevents aggregation. This colloidal silica is commonly used in various applications, including coatings, ceramics, and refractories, due to its ability to improve mechanical strength, thermal stability, and optical properties. The AS-40 grade is characterized by its low sodium content, making it suitable for use in systems where ionic impurities need to be minimized. Its unique combination of particle size, surface charge, and purity makes LUDOX AS-40 a versatile and reliable material for a wide range of industrial and research applications.
