Silicon Carbide SiC Material Properties
Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.

Sanitary Pump Seal Material Overview | Holland Applied
Oct 28, 2013· 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
Silicon Carbide Faces | pump seal is reaction-bonded
Silicon Carbide Faces: Silicon Carbide - Is a bluish-black material created by fusing silica and coke. It is in the same family as Ceramic (due to the Silica), but has much better lubriion qualities and is harder. The most common silicon carbide used in a pump seal is reaction-bonded silicon carbide.
Sselecting the correct hard face material – Mc Nally Institute
Reaction bonded silicon carbide is produced by adding molten silicon to a mixture of silicon carbide and carbon. A reaction between the silicon and carbon bonds the structure while the excess silicon metal fills the majority of the pits left in the resultant material. There is almost no shrinkage during the process. The silicon content is about
