what is cadmium used for

Approximately 86% of the cadmium consumed globally was used in NiCd batteries, 9% in pigments, 4% in coatings and 1% in various uses including alloys, solar cells and stabilizers (Morrow, 2011, p. 10). Cadmium is sensitive to infrared light and is used in applications such as infrared detectors and switches like those found in remote controls. Semi-sealed industrial batteries are important in aeronautical applications, where they are used to start engines and also to provide stand-by power for aircraft systems when the principal power source fails. In 2012, Belgium imported 3,690t of unwrought cadmium (Metal Bulletin, 2009; World Bureau of Metal Statistics, 2012, p. 21; Metal-Pages, 2013; Roskill’s Letter from Japan, 2013b). Bright cadmium yellows, oranges and reds are major pigments for artists' colours where their permanence and opacity are the accepted standards against which other pigments are judged. These lasers are used in fluorescence microscopes. The oxidized form of this metal is commonly used in black and white television phosphors, and blue and yellow phosphors for colored televisions. It is still used today to protect critical components of aeroplanes and oil platforms. Throughout childhood and early adult stages humans inhale about 30 MG. Safety precautions should be used when around Cadmium. Total portable rechargeable battery production in Japan declined by 9% in 2012. But beware, when it is in powder form this element can burn and it can release a highly toxic fume. Cadmium is used in solder and bearing alloys. The replacement of zinc or mercury for cadmium and the replacement of selenium for sulfur forms the spectrum of cadmium pigments that range from lemon-yellow to maroon. The addition of 0.5 per cent by weight of cadmium pigment produces bright transparent glasses with colour ranging from intense yellow through to ruby red depending upon the cadmium sulphide to selenium ratio. It was discovered by the two scientists as an impurity in Zinc Carbonate. The next time you get on a plane, or pick up a pack of rechargeable batteries at your local store, remember that this pure metal has been used in the process to power your devices, and help get you to your destination high up in the sky. The bright colours of cadmium pigments are ideally suited to ceramics, vitreous enamels for glass and porcelain enamels for iron and steel domestic products. Global refined cadmium consumption was 16,200 tons in 2011 (latest data available), a slight drop from that of 2010. Most cadmium produced is electroplated onto steel, iron, copper, brass, and other alloys to protect them for corrosion. Cadmium selenide is used as a red pigment in paints. It is an occupational hazard to some, especially when it is inhaled as a fine dust or fume. After long periods of operation most vented or semi-sealed cells may require electrolyte maintenance by topping up with distilled water.

The coating of photocopier drums is made from cadmium sulphide. Colloidal solutions with cadmium are used in the imaging of biological tissue and solutions under a fluorescence microscope. Small portable NiCds account for 80% of the cadmium consumed for the production of NiCd batteries and are used to power consumer electronics (commonly, power tools). Cadmium salts create bright, brilliant colours that last for long periods of time before showing any signs of fading. Electroplating makes up over 90 per cent of all cadmium consumed in coatings but mechanical plating and vacuum or ion deposition are also of some commercial significance. It has the ability to resist fatigue and friction. This paint is commonly used on brightly coloured buses and trains. Cadmium is used in the nuclear fission process as a barrier to control neutrons. Cadmium sulphite is also used as a yellow pigment in paints. Cadmium sulphite is also used as a yellow pigment in paints. These applications are primarily of two types: industrial and portable batteries. China imported a high percentage of the global cadmium produced outside its borders; 2012 imports of unwrought cadmium totaled 12,600t.

Cadmium was discovered in 1817 by two German scientists, Stromeyer and Hermann. It has a low melting point compared to the transition metals and is mainly found as part of zinc ores. Want to Know it?

Batteries are not the only item it is used in, this metal is also used in the aircraft industry largely due to the fact that when applied it helps prevent corrosion.

In Belgium, Floridienne Chimie S.A., an intermediate processor of cadmium, made up almost all of the country’s cadmium consumption for the production of cadmium compounds (carbonate, nitrate and oxide) and powder, which were then exported to downstream consumers in Asia. Cadmium yellows and reds can have service temperatures well above 3,000 C and are used in coatings for process chemicals and steam pipes. It provides users reliable information and knowledge to the greatest extent. In certain forms this element is toxic causing death at high levels. Other scrap cadmium items that you may find while out scrapping include, silver colored jewelry, old metal toys, fishing lures and sinkers, nuts, screws and bolts. The pigments are fine, discrete particles of coloured powder, with diameters of around 1 gm, which are distributed and suspended in the material to produce a uniformly coloured product. Your email address will not be published. The NiCd battery industry is almost exclusively concentrated in Asia, and leading manufacturers include BYD Co., Ltd. (China), Panasonic Corp. (Japan) and Sanyo Electric Co., Ltd. (Japan). Required fields are marked *, You can use these HTML tags and attributes

. Answers to life's questions, Why are Whale Sharks an Endangered Species, How Many Countries Make up the Commonwealth. Nickel-cadmium batteries for industrial uses are of the vented (or open) or semi-sealed type and may be of pocket plate, sintered plate or fibre structured construction. It is used in black and white phosphors and also in blue and green phosphors in television tubes. Powered by, Trustway Metal - Designed by, Ulysses W. Trustway - Privacy. Cadmium is also used in nuclear reactors where it acts as a neutron absorber. They may be of cylindrical, button or prismatic design. Other uses include standby power for alarm systems, emergency lighting, military communications, solar energy storage, navigation equipment, military equipment and hospital operating theatres. They are also used for memory back-up in computing equipment, military and civil communications, emergency lighting and many other similar applications. Biologically speaking it has been found in the highest concentration in human kidneys! Cadmium, cadmium sulfide and other variations of this metal are used in many things. Greater proportions of pigment (up to about 10 per cent) are employed to make darker decorative glasses.
