Ludox® Colloidal Silica

Colloidal silica is a stable and homogeneous dispersion of amorphous silicon dioxide (SiO2) nanoparticles in water. Colloidal silica is an important industrial product manufactured from the simplest components, sand and water. In addition to being extremely durable, stable and heat-resistant, these particles can be specially produced and chemically customized to provide tremendous potential.

Physical Properties:

• Amorphous (non-crystalline), • Excellent binding ability, • Optical properties. • Refractive index: 1.46 (compatible with many organic systems), • Electrically insulating, • Thermally stable, • High hardness, • Particle structure continuity, • Low solubility, • Smooth surface formation.

Chemical Properties:

• Non-toxic, • High purity, • Weakly acidic, • Chemically stable (especially at low pH), • Surface structure: hydroxyl groups are hydrophilic, hydrogen bonds.       Bahar Aydın Technical Sales and Product Manager Nordmann, Rassmann Turkey
