Selenium

Selenium is a nonmetal, chemically related to sulfur and tellurium, and rarely occurs in its elemental state in nature. It conducts electricity better in the light than in the dark, and is used in photocells. It is found in economic quantities in sulfide ores such as pyrite, partially replacing the sulfur in the ore matrix. The chief commercial uses for selenium today are in glass making and in chemicals and pigments. Uses in electronics, once important, have been supplanted by silicon semiconductor devices. It is used widely in vitamin preparations and other dietary supplements, in small doses. Some livestock feeds are fortified with selenium as well. It is used in the toning of photographic prints. Selenium is a catalyst in many chemical reactions and is widely used in various industrial and laboratory syntheses, especially organoselenium chemistry. It is also widely used in structure determination of proteins and nucleic acids by X-ray crystallography.

Silicon

Silicon is the most common metalloid. It has many industrial uses. It is the principal component of most semiconductor devices, most importantly integrated circuits or microchips. It is widely used in semiconductors because it remains a semiconductor at higher temperatures than the semiconductor germanium and because its native oxide is easily grown in a furnace and forms a good semiconductor/dielectric interface. In the form of silica and silicates, silicon forms useful glasses, cements, and ceramics. It is also a constituent of silicones, a class-name for various synthetic plastic substances made of silicon, oxygen, carbon and hydrogen, often confused with silicon itself. Silicon is an essential element in biology, although only tiny traces of it appear to be required by animals. It is much more important to the metabolism of plants, particularly many grasses, and silicic acid forms the basis of the striking array of protective shells of the microscopic diatoms.

Silicon Carbide

Silicon carbide is a compound of silicon and carbon. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics which are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide as light emitting diodes and detectors in early radios were first demonstrated around 1907, and nowadays silicon carbide is widely used in high-temperature/high-voltage semiconductor electronics.

Silicon Dioxide

Silicon dioxide (Silica) is an oxide of silicon. It is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. It is used primarily in the production of glass for windows, drinking glasses, beverage bottles, and many other uses. The majority of optical fibers for telecommunications are also made from silica. It is a primary raw material for many whiteware ceramics such as earthenware, stoneware, porcelain, as well as industrial Portland cement. It is a common additive in the production of foods, where it is used primarily as a flow agent in powdered foods, or to absorb water in hygroscopic applications. It is the primary component of diatomaceous earth which has many uses ranging from filtration to insect control. It is also the primary component of rice husk ash which is used, for example, in filtration and cement manufacturing. Thin films of silica grown on silicon wafers via thermal oxidation methods can be quite beneficial in microelectronics, where they act as electric insulators with high chemical stability. In electrical applications, it can protect the silicon, store charge, block current, and act as a controlled pathway to limit current flow. A silica-based aerogel was used in the Stardust spacecraft to collect extraterrestrial particles. It is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes. As hydrophobic silica it is used as a defoamer component. In hydrated form, it is used in toothpaste as a hard abrasive to remove tooth plaque. In cosmetics, it is useful for its light-diffusing properties and natural absorbency. Colloidal silica is used as a wine and juice fining agent. In pharmaceutical products, silica aids powder flow when tablets are formed.

Silver

Silver is a transition metal. It has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. The metal occurs naturally in its pure, free form, as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. It has long been valued as a precious metal, and it is used to make ornaments, jewelry, high-value tableware, utensils, and currency coins. Today, silver metal is also used in electrical contacts and conductors, in mirrors and in catalysis of chemical reactions. Its compounds are used in photographic film, and dilute silver nitrate solutions and other silver compounds are used as disinfectants and microbiocides. While many medical antimicrobial uses of silver have been supplanted by antibiotics, further research into clinical potential continues.
