Silicon Carbide (SiC): Properties and appliions | …

Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.

Seal Reliability | Choose the right seal ring material …

2003/1/17· This fine-grain form of silicon carbide has a matrix of silicon carbide powder and free carbon that has been infiltrated with molten silicon. The molten silicon reacts with most of the free carbon to form silicon carbide, but leaves between 10 percent and 12 percent of the silicon unreacted, which provides some inherent lubriion to decrease wear and heat generation.
