Cadmium

Cadmium was discovered simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate. It occurs as a minor component in most zinc ores and therefore is a byproduct of zinc production. It was used for a long time as a pigment and for corrosion resistant plating on steel while cadmium compounds were used to stabilize plastic. With the exception of its use in nickel-cadmium batteries and cadmium telluride solar panels, the use of cadmium is generally decreasing in its other applications. These declines have been due to competing technologies, cadmium’s toxicity in certain forms and concentration and resulting regulations. Cadmium is used as a barrier to control neutrons in nuclear fission. Cadmium oxide is used in black and white television phosphors and in the blue and green phosphors for color television picture tubes. Cadmium sulfide is used as a photoconductive surface coating for photocopier drums. In PVC, cadmium was used as heat, light, and weathering stabilizers. It is used in many kinds of solder and bearing alloys, due to a low coefficient of friction and fatigue resistance. It is also found in some of the lowest-melting alloys, such as Wood's metal. Helium-cadmium lasers are a common source of blue-ultraviolet laser light. They operate at either 325 or 422 nm and are used in fluorescence microscopes and various laboratory experiments. Cadmium is one of six substances banned by the European Union's Restriction on Hazardous Substances (RoHS) directive, which bans certain hazardous substances in electrical and electronic equipment but allows for certain exemptions and exclusions from the scope of the law.

Cadmium Metal

 

Cadmium metal is silver white transition metal, which is available in ingots, rods, sticks, plates, powders, targets and granules. It is soft and toxic, which exist in zinc ore. Cadmium and zinc both are battery material. Cadmium granules slowly oxidize in moist air and lose metal luster. When heating its surface form oxide layer (CdO). With heating cadmium powder can directly react with halogen and other non-metallic elements as sulfurselenium phosphorus. Cadmium ingot is high purity material for semiconductor and reagents.

Calcium Boride

Calcium boride is a compound of calcium and boron. It is an important material due to its high electrical conductivity, hardness, chemical stability, and melting point. It is used in the manufacturing of boron-alloyed steel and as a deoxidation agent in production of oxygen-free copper. It can also serve as a high temperature material, surface protection, abrasives, tools, and wear resistant material. It is highly conductive, has low work function, and thus can be used as a cathode material. It is also a promising candidate for n-type thermoelectric materials, because its power factor is larger than or comparable to that of common thermoelectric materials Bi2Te3 and PbTe.

Carbon

Carbon is nonmetallic and tetravalent-making four electrons available to form covalent chemical bonds. The major economic use of carbon other than food and wood is in the form of hydrocarbons, most notably the fossil fuel methane gas and crude oil (petroleum). Crude oil is used by the petrochemical industry to produce, amongst others, gasoline and kerosene, through a distillation process, in refineries. Cellulose is a natural, carbon-containing polymer produced by plants in the form of cotton, linen, and hemp. Cellulose is mainly used for maintaining structure in plants. Commercially valuable carbon polymers of animal origin include wool, cashmere and silk. Plastics are made from synthetic carbon polymers, often with oxygen and nitrogen atoms included at regular intervals in the main polymer chain. The raw materials for many of these synthetic substances come from crude oil. It can form alloys with iron, of which the most common is carbon steel. Graphite is combined with clays to form the 'lead' used in pencils used for writing and drawing. It is also used as a lubricant and a pigment, as a molding material in glass manufacture, in electrodes for dry batteries and in electroplating and electroforming, in brushes for electric motors and as a neutron moderator in nuclear reactors. Gem quality diamond is used in jewelry, and Industrial diamonds are used in drilling, cutting and polishing tools for machining metals and stone. Carbon black is used as the black pigment in printing ink, artist's oil paint and water colours, carbon paper, automotive finishes, India ink and laser printer toner. It is also used as a filler in rubber products such as tyres and in plastic compounds. Carbon acts as a macronutrient for the body, and is thus greatly required.
