Changing the relation between micro- and mesoporosity in porous glasses: The effect of different factors

- Porous glasses were produced by leaching of two-phase alkali borosilicate glasses.
- Porosity was studied by nitrogen adsorption-desorption equilibrium and kinetic methods.
- The effect of acid and alkaline treatments and chemical composition was revealed.
- Porous glasses are characterized by polymodal size distribution of micro- and mesopores.
- The relationship between micro- and mesoporosity can be varied in a wide range.
