The most striking feature of silicon carbide is its polytypism, i.e. formation of a great nuer of different structural modifiions without any change in composition. Although this feature of silicon carbide was extensively studied, no systematic up to date analysis was done.
obtained – denominated SSiC (sintered silicon carbide) – consist basically of α-SiC grains without an intergranular phase and due to the strong interfacial bonding of the grains a transcristalline fracture mode prevails, resulting in a low fracture toughness of about .
Pump Seal Life Extended From Weeks To Years 01 Deceer 2002 A grade of sintered silicon carbide, containing free graphite evenly dispersed throughout its matrix, has proved to be a very effective replacement for tungsten carbide and other ceramics based pump seal
For example, sintered silicon carbide retains its strength at elevated temperatures and shows excellent time-dependent properties such as creep and slow crack growth resistance. In contrast, reaction-bonded SiC, because of the presence of free silicon in its microstructure, exhibits slightly inferior elevated temperature properties. 7
Abstract: Reaction-sintered silicon carbide (RS-SiC) is a promising material for optical components used in space, or molds for precision glass lens because of its excellent properties. [4] X.

3/9/2013· The strength of the developed structures in some cases exceeded but essentially it remained the same as the fully sintered silicon carbide without the EAL. Ballistic impact tests indied that substantial improvements in the toughness of sintered silicon carbide were achieved by the use of the partially densified silicon carbide EALs.

Morgan Advanced Ceramics Halsic S (pressureless sintered) Silicon Carbide egories: Ceramic; Carbide Material Notes: Exceptionally high-performance ceramics, offering absolute dimensional stability under high loads at elevated temperatures.
The running parts in contact with the material are made of pressureless sintered silicon carbide, including spindle, sliding bearing, moving ring and static ring. Pressureless sintered silicon carbide has smooth surface, higher density and higher strength than reaction sintered silicon carbide, which has replaced reaction sintered silicon carbide.
Sintered Alpha silicon carbide is one of the hardest, most corrosion resistant ceramics commercially available. With no free silicon, this material resists even the strongest acids. Silicon carbide also exhibits excellent thermal conductivity making it a good material for mechanical seals.

SUPERSiC silicon carbide is virtually unaffected by typical semiconductor wet chemistries. Lesser grades of silicon carbide (i.e. sintered) cannot be used in wet chemistries if the protective coating is chipped during normal handling. This chipping will expose the
3M Silicon Carbide Grade F: The All-purpose Grade Good chemical resistance, low specific density, high hardness and wear resistance, outstanding thermal conductivity properties and resistance to fluctuations in temperature. 3M silicon carbide grade F coines all these specific advantages of sintered silicon carbide, particularly for bearings and seals for use in pumps.
Without them, there are a variety of requirements from completely different sectors that would be impossible to fulfil This material (SSiC with graphite) has been developed on the basis of the proven sintered silicon carbide CS10. More Silicon infiltrated Silicon
It held that the use of graphite in a raw batch for forming a sintered silicon carbide body was known, or at least suggested, in the art (cf. documents (10), (9) and (2)). Thus, the replacement of a part of the carbonizable organic material of document (14) with graphite could only involve an inventive step if it was associated with a surprising technical effect.
