Product Description

Lithium Silicate




Li2O :-     2.5% w/w

SiO2 :-   20.5% w/w

Solids:- 23.0% w/w

Weight Ratio = 8.2

Molar Ratio = 4.1

pH = 10.8

Specific gravity = 1.20 at 25 OC

Density = 24.2°Bé

Viscosity = 20 cp



a) Lithium Silicate forms a stable high ratio, low viscosity solution.

b) Once dried, Lithium Silicate is relatively insoluble compared to Potassium and Sodium Silicates.

c) Efflorescence Scale: Li < K < Na

d) Refractoriness: Lithium Silicates have higher melting points and may change the refractory properties of Sodium and Potassium Silicates.

e) Adhesion: Addition of Lithium Silicate to Sodium or Potassium Silicates may improve the adhesion to various different surfaces.
