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
sintered process, SiC grain gets oxidized producing SiO 2 (∼ 32 wt%) and deteriorates the quality of the pro d uct substa ntially. Partially sintered silicon carbide by such a method is a useful material for a varieties of applic a-
The electrochemical behavior of solid‐sintered silicon carbide was investigated under high current densities in alkaline solutions. The use of potentiodynamic as well as chronoamperometric measurements show that the anodic dissolution takes place as a transpassive mechanism under formation of a metastable passive layer.

A Complete Guide to Reaction Bonded Silicon Carbide Reaction bonded silicon carbide is also known as SiSiC or siliconized silicon carbide. This material is produced with the help of a chemical reaction between graphite or porous carbon with melted silicon.A few traces of silicon are left over after the chemical reaction that’s why it is often called siliconized silicon carbide (SiSiC).
1/8/2020· In general, the morphology and mechanical performances of liquid-phase sintered silicon carbide depends on the phase ratio of α-SiC and β-SiC phases, the amount and type of sintering aids, as well as the sintering temperature and times [22,24].
