Aplikasi

      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.

Bahan Baku

Chromium is a chemical element which has the symbol Cr and atomic number 24. It is the first element in Group 6. It is a steely-gray, lustrous, hard and brittle metal which takes a high polish, resists tarnishing, and has a high melting point. The name of the element is derived from the Greek word "chrōma" (χρώμα), meaning colour, because many of its compounds are intensely coloured.
