The compounds based on SiO
2
, are of interest in several fields: as strengthening additives in the potter’s clay materials, insulator
in electronic compounds and in glass industry, concrete, Polymers… Reactivity of SiO
2
depends on the chemical process that
occurs between amorphous or poorly crystallized SiO
2
and the matrix, in turn depends on the surface state of SiO
2
particles. The
silanol groups (SiOH) are the main surface reactive sites and their properties (nature, concentration, distribution, accessibility,
etc.) will determine the chemical activity of the silica. The aim of this work is to study the dependence between structure
properties and reactivity of silica for different SiO
2
compounds. The results show the effect of reaction time and concentration
of basic solution (KOH) on creation of the silanol groups on silica surface. A methodology is proposed to quantify different
silanol groups on silica surface.
