  • Applications

    Chemical name: Silicic acid (H2SiO3), aluminum lithium salt (2:1:1); CAS number: 12068-40-5. Silicic acid (H2SiO3), aluminum lithium salt (2:1:1) is used as a precursor and additive for silicate materials and composite systems, commonly serving as a thickener, binder, and stabilizer in coatings and inks; as a reinforcing filler and processing aid in polymers and plastics; as a support material or catalyst carrier in the chemical industry; contributing to heat resistance and structural stability in ceramics and ceramic-based formulations; potentially applicable in electronics in coatings and dielectric substrates; and as a surface-treatment or dispersing additive in cleaning formulations and coatings.
