  Silicon nitride has an excellent combination of strength, hardness, toughness, corrosion resistance, high temperature capability, and low Shanghai Guangji Silicon Nitride Co.,Ltd.ight 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.
