1.1 Structure and Fragment Morphology

(Silica Sol)

Silica sol is a secure colloidal dispersion including amorphous silicon dioxide (SiO TWO) nanoparticles, generally ranging from 5 to 100 nanometers in size, suspended in a liquid stage– most frequently water.

These nanoparticles are composed of a three-dimensional network of SiO four tetrahedra, developing a permeable and very responsive surface area rich in silanol (Si– OH) teams that govern interfacial habits.

The sol state is thermodynamically metastable, preserved by electrostatic repulsion in between charged bits; surface area charge arises from the ionization of silanol teams, which deprotonate over pH ~ 2– 3, yielding adversely billed bits that repel each other.

Particle shape is generally round, though synthesis problems can affect aggregation propensities and short-range getting.
