Hexoloy SA Protection Sheath | Silicon Carbide Powder
Hexoloy SA is made by sintering silicon carbide powder. This process bonds the powder together to create a self-bonded product which is extremely hard and lightweight. It has a high resistance to corrosion, erosion, high temperature and thermal shock.
Thermodynamics of the Si-C-O system for the production …
The predominance diagrams of the Si-C-O system for 1350 to 2200 C have been constructed thermodynamically by taking into account the presence of liquid silicon monoxide. The high-temperature behavior of various feeds, such as the SiO 2-C and SiO 2-SiC systems, have been calculated as functions of mixing ratio and reaction temperature by using the method of equilibrium mass-balance.

Silicium | Article about Silicium by The Free Dictionary
Silicon forms dark gray crystals with a metallic luster. The crystals have a face-centered cubic diamond-type lattice with the constant a = 5.431 Å and density 2.33 g/cm 3 . A new, apparently hexagonal, modifiion with the density of 2.55 g/cm3 has been obtained at very high pressures.
Superconductivity in heavily boron-doped silicon carbide
28/1/2009· In 2007, we found superconductivity in the stoichiometric composition of carbon and silicon: heavily boron-doped silicon carbide (SiC : B) . One interesting difference between these three superconducting systems is the well-known polytypism in SiC meaning that SiC exhibits various ground states of slightly different energy.
