Nitride Bonded SiC

Nitride bonded silicon carbide materials consist of SiC grains reaction bonded by a silicon nitride (Si3N4) based matrix. The features of this kind of material include an outstanding hot mechanical strength and a low pores size that confers a low permeability to gas as well as a superior infiltration resistance to molten metal and slag and a low wettability.
