Sintered copper may be used as a wicking structure in certain types of heat pipe construction, where the porosity allows a liquid agent to move through the porous material via capillary action. For materials that have high melting points such as molybdenum , tungsten , rhenium , tantalum , osmium and carbon , sintering is one of the few viable manufacturing processes.
Silicon carbide has wide appliions because of stable chemical performance, high thermal conductivity, small thermal expansion coefficient, good wear-resisting performance. Low grade silicon carbide about 85% is an excellent deoxidizer, which can speed up steel making and facilitate the control of chemical composition to improve the steel quality.
2017/2/22· Silicon carbide ceramic: Material: Pressureless sintered silicon carbide (SSIC) Hardness: HV 2400 Density: 3.1 g/cm3 Bending strength: 490 MPa …
Silicon carbide (SiC) ceramic is an ideal material for mechanical seal because of its super hardness, high strength, low friction coefficient, good thermal conductivity, and resistance to friction and wear. However, due to relatively high resistivity of SiC ceramic, the triboelectric charge caused by rubbing of mechanical seal end-faces could not be released. It is terrible that the
History Sintered silicon carbide was patented by the Pittsburgh-based Carborundum Corporation in 1979 under U.S. patent 4,179,299.It is currently held by Saint-Gobain.It was registered and trademarked as Hexoloy in 1984. The first large commercial use for
Hexoloy SE SiC is produced by pressureless sintering of submicron silicon carbide powder in a proprietary extruding process. The sintering process results in a self-bonded, fine grained (less than 10µm) SiC product which is 95% dense. Saint-Gobain can supply
