Key Properties
Silicic acid (dried precipitated) is a hydrated form of silicon dioxide, characterized by its high purity of 99%. This compound is notable for its amorphous structure, which differentiates it from crystalline forms of silica. It serves as a reference compound in various chemical analyses and is widely utilized as a desiccant additive due to its ability to absorb moisture. The compound is particularly important in materials science and silica chemistry, where it plays a crucial role in the development and testing of silica-based materials.
Also known as Silicon Dioxide Hydrate.
