Silicon Carbide

No other company in the world has more expertise with silicon carbide than Saint-Gobain.

In the Beginning

No other company in the world has more expertise with silicon carbide than Saint-Gobain. We invented it, developed numerous variations of it and make more of it for high-performance components than anyone else in the world.

It started about 100 years ago. A struggling scientist, once employed by Thomas Edison, dreamed of becoming wealthy. What better way to riches, he reasoned, than by making artificial diamonds?

The determined young man attached one lead from a dynamo to a discarded plumber's bowl, filled the bowl with clay and powdered coke, inserted the other lead into the mix and threw the switch. Nothing seemed to happen. He was disappointed until he noticed a few bright specks on the end of the leads. When he drew one lead across a pane of glass, it cut like a diamond.

This young scientist, Dr. Edward Goodrich Acheson, had invented silicon carbide (SiC), the first man-made abrasive and substance hard enough to cut glass. Acheson's discovery became Carborundum, the trademark for silicon carbide and the name given to the company he started.

Today

Today Saint-Gobain has earned a reputation for providing advanced, high-tech ceramic components to worldwide markets. These markets span multiple industries, requiring materials that are resistant to extreme temperature, thermal shock, abrasion and corrosion.
