Silicon carbide is considered to be an important struc- tural ceramic material because of a promising combination of properties, such as high oxidation resistance, good me- chanical properties retained to high temperatures, high wear resistance, good thermal shock resistance due to high thermal conductivity, etc.
Silicon Carbide. Sintered silicon Carbide (SiC) and reaction bonded silicon carbide combine excellent corrosion resistance with extreme hardness and high thermal conductivity. Silicon carbide probably has the best resistance to corrosion in acids and alkalis of all advanced ceramic materials.
Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SIC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles.
Silicon Carbide Tubes & Products. It is formed by mixing very fine silicon carbide powder with non-oxide sintering additives at sintering temperature between 2000°C to 2600°C under vacuum or inert atmosphere to form very dense products. Silicon carbide tube and parts can be formed by casting, dry press, extrusion,
In the process of the invention, a formed silicon carbide article is heated in a plasma fired furnace to a sintering temperature of between 2000.degree. C.-2500.degree. C. at a heating rate of 300.degree.
InVinCer Ultron™ Sintered Silicon Carbide (SSiC) is produced using very fine silicon carbide powder containing sintering additives and sintered at 2,200°C in an inert gas atmosphere.
Pressureless sintered silicon carbide is a grade of silicon carbide. It has the lowest strength compared to the other variants of silicon carbide. The graph bars on the material properties cards below compare pressureless sintered silicon carbide to other non-oxide engineering ceramics (top) and the entire database (bottom).
