2018/8/18· Clay graphite crucibles are OK, but they are very susceptible to thermal shock, which means if they are heated too quickly they will crack, silicon carbide crucibles do not suffer from thermal shock. A five to seven year service life from a high quality silicon carbide crucible is not unusual at hobby foundry level, as long as the crucible is properly cared for.

silicon carbide | Encyclopedia

Very pure silicon carbide is white or colorless; crystals of it are used in semiconductors for high-temperature appliions. Silicon carbide fibers, added as reinforcement to plastics or light metals, impart increased strength and stiffness.

Silicon - Energy Eduion

Pure silicon is produced by heating silicon dioxide with carbon at temperatures approaching 2200 C. Silicon can get quite pure, and even different isotopes can get quite pure. Special techniques are able to make silicon that is 99.9999% pure Si-28.


Pure silicon carbide is colourless and transparent. The green to black colour of the industrial product results from impurities, mostly iron. The green specimen is a somewhat purer, slightly harder, but more friable form (Wright, 2006). Although silicon carbide has

Silicon carbide | Cerámica Wiki | Fandom

Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive.

The Creation of Silicon Carbide Revolutionary …

Compared to silicon or gallium arsenide, the Silicon carbide (SiC) is a rather young base material in the semiconductor industry but its origins date back to the end of the 19th century. In 1891, Edward Acheson developed a method for producing crystalline SiC as an abrasive material — a method still in use today.
