What is Asymmetric SiO2 structural units modification by Li 2O and their effect on optical and mechanical properties of soda lime silicate glasses about?
The composition of 64SiO 2 - 16Na 2 O - 12CaO - 2Al 2 O 3 - (6 - x)MgO - xLi 2 O (x = 0, 2, 4 and 6) prepared by the melt quench technique to study the effect of Li 2 O on optical and mechanical properties. The X-ray diffraction spectra confirmed the amorphous nature of all the quenched samples. The density, hardness, and elastic modulus are found to be decreased with the addition of Li 2 O modifier instead of MgO. On the other hand, the brittleness, optical band gap, and transparency of the glasses are increased due to the conversion of bridging oxygens into non-bridging oxygens. Interestingly, the asymmetric structural units of SiO 2 ( Q 3 and Q 1 ) increased instead of Q 2 with the replacement of MgO by Li 2 O. The highest transparency is observed with the highest content of Li 2 O (6 mol%). The transparency along with other properties are found to be either comparable or higher than the commercially available windshield glasses. Thus, these glasses can be used as windshield glass in automobiles.
