Appearance
Chromium is a blue - white, hard metal, capable of taking a high polish.

Source
Chromium is found principally in the ore Chromite, which is found in many places including the former USSR, Turkey, Iran, Finland and the Phillipines. Chromium metal is usually produced by the electrolysis of Chromium (III) oxide by Aluminium, or electrolysis of Chrome alum.

Uses
Chromium is used to harden Steel, to manufacture Stainless Steel and to produce several alloys. It is also used in plating as it prevents corrosion and gives a high - lustre finish. It is also used as a catalyst.

Chromium compounds are valued as pigments for their vivid green, yellow, red and orange colours. The Ruby takes its colour from Chromium, and Chromium added to glass imparts an emerald green colour.

General Information
Chromium is an essential trace element, but is carcinogenic in excess. Chromium compounds are toxic.
