The boules may be either semiconductor (e.g. electronic chip wafers, photovoltaic cells) or non-conducting inorganic compounds for industrial and jewelry use (e.g., synthetic ruby, sapphire). Single crystal ingots of metal are produced in similar fashion to that used to produce high purity semiconductor ingots, [3] i
Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment, and jewelry. Palladium is a key component of fuel cells, in which hydrogen and oxygen react to produce electricity, heat, and water. Ore deposits of palladium and other PGMs are rare.
The Tanaka Kikinzoku Group, founded in 1885, is a Japanese manufacturer of precious metals materials focusing mainly on products for the electronics, semiconductor and automotive industries. [2] Tanaka's European subsidiary is Tanaka Kikinzoku International (Europe) GmbH in Frankfurt , Germany and its US subsidiary is Tanaka Kikinzoku ...
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
The best known precious metals are the precious coinage metals, which are gold and silver. Although both have industrial uses, they are better known for their uses in art , jewelry , and coinage. Other precious metals include the platinum group metals: ruthenium , rhodium , palladium , osmium , iridium , and platinum , of which platinum is the ...
The dominant uses of iridium are the metal itself and its alloys, as in high-performance spark plugs, crucibles for recrystallization of semiconductors at high temperatures, and electrodes for the production of chlorine in the chloralkali process. Important compounds of iridium are chlorides and iodides in industrial catalysis.
The TSMC plant is the first step in what Tokyo hopes will be a revival of Japan’s chip industry. In June 2021, the Japanese government released a strategy that put semiconductors at the center ...
Indium is a technology-critical element used primarily in the production of flat-panel displays as indium tin oxide (ITO), a transparent and conductive coating applied to glass. [ 15 ] [ 16 ] [ 17 ] Indium is also used in the semiconductor industry , [ 18 ] in low-melting-point metal alloys such as solders and soft-metal high-vacuum seals.
