chro·mi·um

 (krō′mē-əm)
n. Symbol Cr
A lustrous, hard, steel-gray metallic element, resistant to tarnish and corrosion and found primarily in chromite. It is used in the hardening of steel alloys and the production of stainless steels, in corrosion-resistant decorative platings, and as a pigment in glass. Atomic number 24; atomic weight 51.996; melting point 1,907°C; boiling point 2,671°C; specific gravity 7.15; valence 2, 3, 6. See Periodic Table.

[From French chrome; see chrome.]

While demand in microscopy, ophthalmics, high power lasers, and optical communications is also expected to aid the continuous expansion of the optical coatings market, it was highlighted in the report that government action against chromium trioxide (Cr6) plating could potentially act as a market deterrent.
Due to concerns raised by REACH regarding the use of chromium trioxide, many architectural coaters have now moved to chrome free alternatives.
Subchronic inhalation toxicity of soluble hexavalent chromium trioxide in rats.
Unlike the oxidation conditions which employ toxic transition metal reagents such as chromium trioxide and strong oxidizing reagents such as potassium permanganate, the BAIB-TEMPO oxidation offers a mild alternative which produces less toxic byproducts and high product yields.
