What exactly is silicon?

Silica is another name for silicon oxide, the most common type being SiO2. It is the crystalline form in nature (quartz sand) and is the most abundant component of the earth's crust. Amorphous silica, on the other hand, is manufactured industrially in a variety of forms, including silica gel, precipitated silica, fumed silica, and colloidal silica.

What does "colloid" mean?

A colloid is a stable dispersion of particles -- particles small enough that gravity does not cause the particles to settle, but large enough not to pass through the membrane, allowing other molecules and ions to pass freely. The particle size range is from about 1 to 100 nm.

How is silica gel different from fumed silica, fused silica, or precipitated silica?

Silica is distinct from other types of silica in several ways. The most notable difference is in liquid form rather than powder form. Furthermore, it has the widest surface area and its aggregate size can be as small as the actual size of the primary particles.

Acid Series Colloidal Silica/Silica Sol

Acidic silica sol is a colloidal solution formed by uniform diffusion of silica particles in water. The pH is 2 to 6. It has many excellent properties and characteristics.
