Silicon carbide, specifically reaction bonded and self-sintered silicon carbide, offers superior strength, abrasion resistance, and thermal conductivity to alumina ceramic.
Reaction bonded silicon carbide is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon.  The silicon reacts with the carbon forming silicon carbide.  The reaction product bonds the silicon carbide particles.  Any excess silicon fills the remaining pores in the body and produces a dense SiC-Si composite.
Sintered silicon carbide is a premium version of silicon carbide. It contains no free graphite or silicon. Sintered silicon carbide is Waukesha's hardest seal face for sanitary pumps.  It contains no silicon that can leach into the process, is excellent in an oxidizing environment, and has good thermal shock resistance due to low thermal expansion coefficient and high thermal conductivity.
In summary, silicon carbide's combination of hardness, strength, and temperature resistance gives it excellent capabilities for services in a wide range of applications where high speeds, high pressures, and chemical and abrasion resistance are required.
