Silicon Nitride (Si3N4) Parts

Silicon Nitride (Si3N4) Parts


Silicon nitride [Si3N4] is a ceramic, the peculiarity of which lies in its increased strength characteristics and increased wear resistance, relative to other types of ceramic materials. Therefore, it is best used in structures where high strength of the product and its resistance to high temperature changes are necessary.


Due to their mechanical characteristics, products made using silicon nitride perfectly withstand conditions of prolonged thermal cycling, shocks, tests with increased friction, as well as interaction with aggressive media.
