Silicon Nitride Ceramic Substrates (Si3N4)
Silicon nitride [Si3N4] is a ceramic, the features of which are 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.
