Element Description

Chromium is a steel-gray, lustrous, and hard metal that finds wide use as a catalyst or in alloys. All chromium compounds have intense and varied colors. Chromium is used as a hardener in steel, for the manufacture of stainless steel and many useful alloys. It is also employed to give glass an emerald green color. Chromium does not oxidize in air, even in extreme moisture.
