What is the difference between silica and colloidal silica?

What is the difference between silica and colloidal silica?

Summary – Colloidal Silica vs Reactive Silica The key difference between colloidal silica and reactive silica is that colloidal silica is the polymeric form of silicon, whereas reactive silica is the non-polymeric form of silicon.

What does colloidal silica do?

Depending on the size of its constituent particles, colloidal silica may be used to enhance the movement of materials or to increase surface friction. Colloidal silica is used in a broad range of industries and applications, including: Densification of concrete, cement, and other materials.

Is colloidal silica the same as fumed silica?

Fumed Silica also known as Colloidal Silica is a filler often used in epoxy. Silica fume is a by-product of silicon metal production and is used mainly as a concrete additive where it adds strength and longevity to the concrete.

What does silica do to the body?

Silica is an important trace mineral that provides strength and flexibility to the connective tissues of your body — cartilage, tendons, skin, bone, teeth, hair, and blood vessels. Silica is essential in the formation of collagen, the most abundant protein found in your body.

Is silica A colloidal?

In the most general terms colloidal silica is a dispersion of amorphous silicon dioxide (silica) particles in water. These amorphous silica particles are produced by polymerizing silica nuclei from silicate solutions under alkaline conditions to form nanometer sized silica sols with high surface area.

Can you eat fumed silica?

* Do not eat, smoke, or drink where Silica, Amorphous (Fume) may be present since the chemical can be swallowed. Wash hands carefully before eating, drinking, smoking, or using the toilet.

Is colloidal silica hazardous?

Skin corrosion/irritant: Irritating to skin. Serious eye damage/irritant: Risk of serious damage to eyes. Target organ toxicity (single exposure): May cause respiratory/skin irritation. Target organ toxicity (repeated exposure): May cause respiratory/skin irritation.
