C HR 0 MIU M HE only workable source of the element chromium is chro T mite, a compound of chromium, iron and oxygen mined in Russia, Africa and Turkey. Chromium is known everywhere as the plating on taps, hardware and motor fittings, but it has other and more important applications. Alloyed with steel, for example, it imparts superior strength and surface hardness, and it is from chromium that stainless steel derives its resist- ance to corrosion. As well as being the source of chromium, crude chromite ore is used to make heat-resisting firebricks and cements for the construction of furnaces Chromium derives its name from the Greek Xpwpa meaning colour, be- cause its compounds are almost always coloured. Known 38 chrome pigments, some of these-_the chromates of lead, zinc and barium for example-are used extensively for colouring paints, linoleum; rubber and ceramics Chromium sulphate is important in tanning, and potassium dichromate in the dye- ing of wool, sikk and leather. Other chromium compounds are used in photography and in the manufacture of safety matches. ICI makes a complete range of chrome pigments for the paint; linoleum and rubber industries, besides employing chromium compounds as catalysts in the manufacture of aviation petrol and methanol, an industrial alcohol: ICL IMPERIAL CHEMICAL INDUSTRIES (NZ) LTD_ A "Vital" 0 2 Difference Vi-Max made from selected wheat Andi Ca with extra wheat germ added is not devitalised.
