Molar ratio

Characterizies the chemical composition and/or the alkalinity of the alkali water glass solution according to eq. 1:

Eq. 1:MV= frac{Mol - \%SiO_2}{Mol - \%Na_2O} oder frac{Masse - \%SiO_2}{Masse - \%Na_2O}cdot 1,03


Water glass binders used for casting mold materials usually have molar ratios of 2.5: 1 to 2.8: 1.
