Lithium Silicate is the smallest stable Silica on earth. One Silicon dioxide (SiO2) molecule is attached to a Lithium atom.

  • Lithium Silicate forms a stable high ratio, low viscosity solution.
  • Once dried, Lithium Silicate is relatively insoluble compared to Potassium and Sodium Silicates.
  • Efflorescence Scale: Li < K < Na
  • Refractoriness: Lithium Silicates have higher melting point and may change the refractory properties of Sodium and Potassium Silicates.
  • Adhesion: Addition of Lithium Silicate to Sodium or Potassium Silicates may improve the adhesion to various different surfaces.

APPLICATIONS

  • Concrete Surface Treatment – Densification and Waterproofing 
  • Concrete Admixture
  • Coatings, usually as part of the binder system
  • Welding Rod Binder Additive
  • Refractory Applications
  • Flame Retardant
  • Ceramics, Glazes
