Pressureless sintered silicon carbide (SSIC) is
produced using very fine SiC powder containing sintering
additives. It is processed using forming methods typical for
other ceramics and sintered at 2,000 to 2,200° C in an inert gas
atmosphere. As well as fine-grained versions, with grain sizes
< 5 ?m, coarse-grained versions with grain sizes of up to 1.5
mm are available. SSIC is distinguished by high strength that
stays nearly constant up to very high temperatures (approximately
1,600° C), maintaining that strength over long periods!
This material displays an extremely high corrosion resistance in
acidic and basic media, and this too is maintained up to very
high temperatures. The coarse-grained versions offer particular
advantages. These properties are outstanding among
high-temperature ceramics, and are complemented by high thermal
shock resistance, high thermal conductivity, high resistance to
wear, and a hardness close to that of diamond. Thus, SSIC is
ideal for extremely demanding applications, for example, slip
ring seals in chemical pumps, bearing bushes, high temperature
burner nozzles, or as kiln furniture for very high application
temperatures. The use of SSIC with graphite inclusions improves
the performance of tribological systems.
