After knowing the everyday uses of semiconductor here we see why semiconductors are used in daily life applications. Ornate Saris & Fabrics What: The tradition of using gold ‘zari’ - which sees silver threads being plated with gold- in saris dates to the Mughal era, when it became a preference among royalty and the nobility. The main use of gallium is in semiconductors where it is commonly used in microwave circuitry and in some infrared applications. It is used as an ingredient in red signal flares and phosphors and is the principal health hazard in radioactive fallout. Uses. Germanium dioxide can be used as a catalyst in the production of the PET plastic used in many bottles, though it is rarely employed for this in Europe and the US. Four other elements expand when they freeze; silicon, bismuth, antimony and gallium. infrared optics. But did you know that this much-cherished metal is also used in abundance in all these everyday items? It is still primarily the pure element that has a role, if rather more specialized than it first was, in our electronics and communications. Germanium really took off with the development of the transistor, a solid state version of the triode valve. Aluminum. It is theorized that embedding germanium into cotton garments is an effective way to use the transdermal effect to create a micro electromagnetic field, leading to increased circulation and affecting the inflammatory process. Strontium (Sr), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table. Germanium compounds are used for polymerization catalysts. Germanium is used in transistors and in integrated circuits. Countless objects that simplify as well as increase the quality of our daily life are partly made of aluminum, e.g. Used with the right technologies, silicone rubber provides innovative manufacturing solutions and design opportunities. Germanium is also used as an alloying agent, a catalyst, and as a phosphor for fluorescent lamps. About 40 percent of the germanium produced in the United States is now used … Germanium has an atomic weight of 73 atomic mass units. This still accounts for about 15 percent of the germanium produced. atomic number 38 atomic weight 87.62 melting point 769 °C (1,416 °F) It can also be used to make signs that have a yellowish- green glow to them. Devices using caesium include photomultiplier tubes, video camera tubes. Barium Sulfate in Oil Production: Barium Sulfate is primarily used when drilling for new oil wells, which is by far the most common use for barium.It is combined with water and some other minerals to create drilling mud. Germanium is a chemical element with the symbol Ge and atomic number 32. 20 Previous low-level observational studies have suggested that germanium-infused garments may provide improved clinical outcomes in osteoarthritis.
