But it is seldom mentioned in this field, which is drying the sodium silicate solution to gain the hydrated silicate glass.
Dent Glasser and Lee [7] studied the drying of sodium silicate solutions and the structure of the obtained silicate glass.
Roggendorf and BÖschel [8] did some research on the glass transition of the dried aqueous sols.
These types of hydrated silicate glass are all soluble with poor chemical durability.
That might be the reason why the colloid chemistry method is rarely adopted in this field.
