Quote from Wikipedia article [ link to en.wikipedia.org (secure)] " Virtually all the silicon carbide sold in the world, including moissanite jewels, is synthetic.While rare on Earth, silicon carbide is remarkably common in space. It is a common form of stardust found around carbon-rich stars, and examples of this stardust have been found in pristine condition in primitive (unaltered) meteorites. The silicon carbide found in space and in meteorites is almost exclusively the beta-polymorph. Analysis of SiC grains found in the Murchison meteorite, a carbonaceous chondrite meteorite, has revealed anomalous isotopic ratios of carbon and silicon, indicating that these grains originated outside the solar system." |

Silicon Carbonate is used commonly for thermocouple sheaths to prevent wear, we use them in 24" and 33"lengths that are 2" in diameter. Pretty pricey though. |

Sic is the new revolution in semi-conductors. They simulate the conditions of a star to make it. Crazy stuff. It took six days to cut through it with a special saw to make wafers of it that are about the size of a CD. Now they are also using lasers in a cool way that cuts the time down. Company was once known as Cree, whom mainstreamed the LED and changed the world. Now they are doing it again with Sic chips. Wolfspeed. Good stock to buy on a dip. |
