Figure 1 shows the XRD patterns of sodium silicates obtained by drying the sodium silicate solution at 200 °C for 24 h and 14 days. Only one broad peak was observed in Fig. 1a, and this indicates that drying the sodium silicate solution for 24 h yielded an amorphous sodium silicate. In Fig. 1b, the sharp peaks emerged by extending the drying time to 14 days, and the …
