Shanghai Guangji Silicon Nitride Co.,Ltd.

Silicon nitride has an excellent combination of strength, hardness, toughness, corrosion resistance, high temperature capability, and low weight that make it useful for many applications involving high contact stress sliding or rolling contact, corrosive chemicals, or high temperatures. By plasma-enhanced chemical vapor deposition?PECVD?, our company successfully produced nano-powder silicon nitride, which can be used as a substitution to conventional Si3N4, to produce structural or functional materials. Take advantages of nano-material, our Si3N4 powder can be used in many respects, including MMC(metal matrix composite), PMC(polymer matrix composite) as well as CMC( ceramic matrix composite). Our company focused on producing nano-powders including Si3N4, at the same time, we are glad to cooperate with our powder users, to develop nano-powder silicon nitride related products. Key Properties: High strength over a wide temperature?range High fracture toughness High hardness Outstanding wear resistance, both impingement and frictional modes Good thermal shock resistance Good interface compatibility Good chemical resistance Typical Uses Rotating bearing balls and rollers Cutting tools Engine moving parts - valves, turbocharger rotors Engine wear parts - cam followers, tappet shims Turbine blades, vanes, buckets Metal tube forming rolls and dies Precision shafts and axles in high wear environments
