Reaction Sintering of Carbon Fiber Reinforced Silicon

SEM showed that short carbon fibers could disperse uniformly in the preforms and sintered carbon fiber reinforced silicon carbide composites (C f /SiC). The mechanical test results showed that the strength decrease from 286 MPa for RB-SiC to 231 MPa for C f /SiC, however, the fracture toughness of Cf/SiC increased from 3.65 MPa m 1/2 to 5.28 MPa m 1/2 compared with RB-SiC.

2003/1/1Sintering of silicon carbide activated with boron and carbon takes place at high temperatures. Shrinkage of the material and varying pore morphology ( Fig. 2, Fig. 3 ), begins at temperatures higher than 1600 C, full densification is attained at temperatures exceeding 2000 C.

Sintered Silicon Carbide

Graphite Loaded Sintered Silicon Carbide The free graphite improves lubricity for greater dry run survivability and better thermal shock resistance than conventional sintered materials. Increased PV (pressure velocity) capability between hardface mating pairs, due to the presence of graphite, makes PGS-100 the best solution for all types of hardface pair sealing applications.

Silicon carbide

Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).
