Electronic grade silica sol has significant characteristics such as high purity, high molecular weight and stable chemical properties. Its purity is usually higher than 99.99%, and can even reach 99.9999%, ensuring its safety for use in the electronics and chemical industries. In addition, electronic grade silica sol has a large specific surface area, which can reach more than 800m²/g, providing more adsorption sites and thus having excellent adsorption performance. These properties make electronic grade silica sol have broad application potential in multiple high-tech fields.
