Levasil Colloidal Silica aqueous dispersions are available in a variety of grades determined by particle size, structure, concentration, pH, surface charge and surface modification. It is a versatile, inorganic material, also known as silica sol, that can be used for many different industrial functions.

  • Concentrations: 7– 50% SiO2
  • Particle size distributions: narrow, medium or wide
  • Structures: Discrete particles or chains
  • Particle diameters: 2–150 nm (nanometer)
  • Surface areas: 30-1100 m2/g
  • pH: 2–12
  • Modifications: ammonium, aluminate, chloride, silane, deionized
  • Morphology: Spherical or irregular
