Silicon - Wikipedia

Silicon carbide is rapidly attacked by chlorine gas, which forms SiCl 4 and carbon at 100 °C and SiCl 4 and CCl 4 at 1000 °C. It is mostly used as an abrasive and a refractory material, as it is chemically stable and very strong, and it fractures to form a very sharp cutting edge.

Silicon carbide - Wikipedia

Silicon carbide is an important material in TRISO-coated fuel particles, the type of nuclear fuel found in high temperature gas cooled reactors such as the Pebble Bed Reactor. A layer of silicon carbide gives coated fuel particles structural support and is the main diffusion barrier to the release of fission products.

Reference Materials - Sympatec

Reference material is used for re-certifiion of a Sympatec instrument. Sympatec prefers to test the precision of the instruments by real powder instead of reticles (transparencies with images of particles), because the proper function of the dispersing system, which is essential to a precise measured result, can only be tested by real powder.

Material Properties Charts - Ceramic Industry

Silicon Carbide (SiC). Silicon carbide has outstanding wear and thermal shock resistance. It has good mechanical properties, especially at high temperatures. It is a semiconductor material with electrical resistivities in the 10^5 ohm-cm range. It can be processed to a very high purity. Silicon carbide is used extensively for mechanical seals

Corrosion characteristics of silicon carbide and silicon

is shown in Fig. 1. The bulk ceramic material usually may be assumed to have a film or scale on its surface that differs chemically from the bulk material. For either silicon carbide or silicon ni- tride, the film is usually a critically important silica layer. The bulk ceramic and its surface scale form a solid body that is exposed to a hot

MOISSANITE (Silicon Carbide) - Amethyst Galleries'' Mineral

Moissanite is a mineral that was first discovered in fragments of the meteorite at Diablo Canyon or Meteor Crater in Arizona. It was named in honor of its discoverer, Nobel Prize winner Dr. Ferdinand Henri Moissan. Synthetic moissanite is also known as silicon carbide after its chemistry and by the trade name, carborundum.In the meteoritic material, moissanite is associated with tiny diamonds.
