A Burning Need
Gas fireplaces burn cleaner and offer greater control than wood-burning fireplaces. Many homeowners turn to realistic-looking artificial logs made with colloidal silica. These particles bind together heat-resistant fibers, forming a material that’s molded into ceramic-based logs that can take the heat for up to a decade.

Nice Fire
Compared to wood-burning fireplaces, gas fireplaces can provide greater heating efficiency, have lower annual costs, and emit 99% fewer particles than wood-burning fireplaces.

Raw exhaust from car engines can be toxic. Modern cars remove gases, like carbon monoxide, with catalytic converters. Colloidal silica can play multiple roles in the converter.

A Converter Closeup
LUDOX colloidal silica is included in many components of the catalytic converter, serving as a high-temperature glue for metal oxides and as the silica source for the synthesis of the zeolite catalyst (schematic shown left).

Today’s golf clubs are made using a technique with roots in antiquity: investment casting. Modern investment casting relies on molds formed from colloidal silica-based ceramics.

Time to Shape Up
Investment casting is based on a millennia-old method called lost wax casting. A wax form is embedded in plaster; the wax is then melted away, leaving an empty cast for molten metal. Modern colloidal silica-based molds can withstand the blazing temperatures needed to precisely shape aluminum, titanium, or steel.

Untreated metal pans may seem smooth, but those surfaces contain microscopic scratches that can turn your meal into a clingy mess. Sol-gel ceramic coatings made with colloidal silica form an even veneer that fills in surface scratches to create smooth non-stick cookware.

Compared to other non-stick
surfaces, sol-gel coatings are
harder and can function at higher
temperatures, up to 450°C/840°F. A conventional coating will begin to degrade at 350 ºC (662 ºF), releasing potentially hazardous fine particles and gaseous compounds.

Glossy cast-coated papers are perfect for posters and packaging with bright, eye-catching colors—but only if they provide a good surface for ink retention. An outer layer of a colloidal silica-based coating provides a bright, clear top coat.

Printed With Care
Coating inkjet or photo paper with colloidal silica allows inks to adhere to the surface while water is absorbed by the receiver layer. This coating also prevents the ink from bleeding into the material below, resulting in crisp and clear images and preserving the glossy appearance of the paper.
