Silicon carbide powder has a black color when the purity is low and products with purity higher than 90% is green. SiC grains can be bonded together by sintering to form ceramic materials that could be used as car brakes or bullet proof material for ballistic vests.
Objectives To investigate the relationship between dust exposure and annual change in lung function among employees in Norwegian silicon carbide (SiC) plants using a quantitative job exposure matrix (JEM) regarding total dust. Methods All employees, 20–55 years of age by inclusion (n=456), were examined annually for up to 5 years (1499 examinations). Spirometry was performed at each
Silicon carbide diodes and MOSFETs can operate at much higher temperatures than common silicon. Silicon power units can only work efficiently up to 150°C. On the contrary, SiC can function at temperatures that reach 200°C and even above the temperature; however, most commercially available components are still esteemed at 175°C.
Siliciumkarbid, også kaldt karborundum, carborundum, har den kemiske forkortelse SiC, som består af silicium og carbon. Det er et industrielt fremstillet materiale, som anvendes til slibeprodukter og som tilsætningsstof. Materialet er noget af det hårdeste, som findes, med værdien 9,5 på Mohs hårdhedsskala; kun diamanter er hårdere med

Silicon, a nonmetallic chemical element in the carbon family that makes up 27.7 percent of Earth’s crust; it is the second most abundant element in the crust, being surpassed only by oxygen. Learn more about the characteristics, distribution, and uses of silicon in
Using first-principles calculations, we study the work function of single-wall silicon carbide nanotube (SiCNT). The work function is found to be highly dependent on the tube chirality and diameter. It increases by decreasing the tube diameter. The work function of zigzag SiCNT is always larger than that of armchair SiCNT. We reveal that the difference between the work function of zigzag and
Silicon carbide superjunction Schottky junction diodes China’s Zhejiang University claims the first functional silicon carbide (SiC) superjunction (SJ) device, in the form of a Schottky diode [Xueqian Zhong et al, IEEE Transactions On Electron Devices, vol65, p1458, 2018].
One-dimensional silicon−carbon nanotubes and nanowires of various shapes and structures were synthesized via the reaction of silicon (produced by disproportionation reaction of SiO) with multiwalled carbon nanotubes (as templates) at different temperatures. A new type of multiwalled silicon carbide nanotube (SiCNT), with 3.5−4.5 Å interlayer spacings, was observed in addition to the

Silicon carbide is a semiconductor and, like silicon, can be doped with trace amounts of other elements to form diodes, junctions and transistors. Semiconducting silicon carbide first found appliion as a detector in early radios at the beginning of the 20th Century.
Traditionally, pump manufacturers used SiC (silicon carbide) for bushings and bearings in these pumps because of its high hardness and ability to withstand abrasive wear in solid media. Since the early 1980s, OEM pump manufacturers have been using sintered SiC bearings for the stationary and rotating components of tubular casing pumps.
