What is the difference between colloidal silica and silica sol?

Binder Applications

LUDOX® colloidal silica forms strong ionic and hydrogen bonds with granular and fibrous material.  These bonds are thermally stable and chemically inert making them especially useful for:

• Investment Casting Slurries
• Vacuum Formed Refractories
• Specialty Coatings
• Catalysts
• Insulation Board

Surface Modification Application

The silica particles in LUDOX® adhere well to many surfaces via ionic and hydrogen bonding.  Once applied to a surface the silica particles provide an increased coefficient of friction that is useful for:

• Paper & cardboard
• Flooring
• Polishing Slurries
• Industrial and architectural coatings

Flocculant Applications

LUDOX® colloidal silica is available in grades with anionic sol charge as well as cationic sol charge.  When added to solutions  LUDOX® particles bond ionically with particles of the opposite charge and fall out of suspension.  This makes LUDOX® an excellent flocculant for:

• Paper retention and drainage
• Beverage fining (beer and wine)
• Insulation board

The characteristics of LUDOX® Colloidal Silica and it's usefulness as a binder and surface modifier are further highlighted in the short video below.
 

Today, LUDOX® colloidal silica is used in applications ranging from a high temperature binder for the production of aerospace parts to a fining agent used to produce beer and wine. LUDOX® functions in commercial applications in three major ways; as a binder, surface modifier, and flocculant.LUDOX® colloidal silica forms strong ionic and hydrogen bonds with granular and fibrous material.

Of all the oxide minerals in the Earth&#;s crust, silicon dioxide, or silica, is the most abundant. It is present in not only in combination with other oxide minerals but also in its isolated forms such as sand. The semi-precious mineral opal is a form of amorphous silica that has been prized for centuries.

Besides being the most abundant mineral on the Earth, it is also very important to life on our planet. Diatoms, a type of phytoplankton forming the base of the ocean&#;s food chain, have skeletons composed of silica.  Many plants use silica to stiffen stems for holding fruit and to form external needles for protection. The role of silica is less obvious in animals, but each one of us contains about half a gram of silica &#; without which our bones, hair, and teeth could not be formed.

Not only does silica play an important role in biology, it had played an important role in civilization. Flint is a form of silica that was used in ancient tools.The sand used in pottery is also a form of silica. Two-thousand year-old Roman cement contains amorphous silica from volcanic ash which helps give it high strength and durability. Present technology would be very different without the silica used to create the catalysts of our oil refineries, bind the molds for casting super-alloys, form modern glass and ceramics, and polish electronic materials.
