Hydrothermal synthesis of hydrated layered polysilicate magadiite from coarse quartz glass blocks

We herein report a new method of synthesizing highly crystalline hydrated layered polysilicates (HLSs) using a coarse quartz glass block as a precursor. Magadiite, a type of HLS, is synthesized through hydrothermal reactions at 150 °C with a SiO2/NaOH/H2O ratio of ≈4.4/1.0/81.1. The results showed t...

Zusammenfassung:We herein report a new method of synthesizing highly crystalline hydrated layered polysilicates (HLSs) using a coarse quartz glass block as a precursor. Magadiite, a type of HLS, is synthesized through hydrothermal reactions at 150 °C with a SiO2/NaOH/H2O ratio of ≈4.4/1.0/81.1. The results showed that when the particle size of the precursor was classified as
