Natural alkali solar glass

Can glass be used as a raw material for alkaline activation?

This comprehensive overview results in the following conclusions: Glass has the potential to serve as the sole raw material for alkaline activation, functioning independently of its chemical composition and the molarity of the alkaline solution.

How are alkali silicate glasses prepared?

Alkali silicate glasses were prepared from mixtures of reagent grade SiO 2, Na 2 CO 3, and K 2 CO 3 powders. The mixtures were melted at 1923 K in air. Each melt was quenched and annealed at the glass transition temperature and then cooled slowly by 1 K/min. The nominal and analyzed compositions of the glasses are listed in Table S1.

What is the molecular mechanism of mild alkali-activated glasses?

This suggests that the molecular mechanism of mild alkali-activated glasses is similar to glass corrosion. Due to the limited molarity, the alkaline solution does not allow for the complete dissolution of the glass used as raw material, but only affects the surface of the glass particles.

Does sodium-potassium silicate glass have a mixed alkali effect?

A novel topological analysis using persistent homology found that sodium-potassium silicate glass shows a significant reduction in large cavities as a result of the mixed alkali effect. Furthermore, a highly correlated pair arrangement between sodium and potassium ions around non-bridging oxygen atoms was identified.
