Metrosil''s larger varistors to protect electrical generators
The 8000 Series has been developed around an improved ergonomic structure, an industry first, providing not only protection for the varistor discs, but also simplifying the installation of the units. Metrosil, a manufacturer of silicon carbide non-linear resistors (called varistors) announced the launch of its new range of De-Excitation Units – the “Metrosil 8000 Series”, designed to

Rock Tuler Grit and Silicon Carbide Grit Kits
1) Silicon carbide grit is very hard. It is much harder than the rocks that most people tule. On the Mohs Hardness scale silicon carbide has a hardness of 9 to 9.5 while commonly-tuled rocks such as jasper, agate, quartz and petrified wood have a Mohs
The long history of light-emitting diodes - Electronic …
2011/8/31· The silicon carbide used in the ’s-whisker detectors at the time was an indirect bandgap semiconductor, and thus inefficient (the light produced was faint at best). In 1955, Rubin Braunstein of the Radio Corporation of America reported infrared emission being generated by simple diode structures when using gallium-arsenide, gallium-antimonide, indium-phosphide, and silicon-germanium alloys.
Microchip Technology Silicon Carbide (SiC) Semiconductors are an innovative option for power electronic designers looking to improve system efficiency, smaller form factor, and higher operating temperature in products covering industrial, medical, military
Yale Researchers ''Look'' Deep Inside a Diamond Planet
Any silicon carbide in a planet that did not decompose would undergo this transition, likely having a dramatic effect on the interior dynamics, the researchers said. “Through these experiments, we are beginning to develop a picture of what the interior of a carbon-rich planet might look like,” said Kanani Lee, the study’s principal investigator and an associate professor of geology and
Varistors: Ideal Solution to Surge Protection | Power …
A high α implies a better clamp; zinc oxide technology has enabled varistors with a in the range 15 to 30—significantly higher than earlier generation devices such as silicon carbide varistors. The V-I behavior of a varistor is shown in Fig. 1 highlighting the distinct operating zones of the varistor.
Sintered Silicon Carbide SSiC Ceramic is produced using very fine silicon carbide powder containing sintering additives. It is processed using forming methods typical for other ceramics and sintered at 2,200 C in an inert gas atmosphere.
