Silicon nitride Piston/Plunger is a material with high fracture toughness and excellent thermal shock resistance,and in recent years it is also used as a substitute for molds.It is used in the filed of machinery, electronic, semiconductor, chemical, petroleum, smelt.
Silicon nitride piston/plunger's main applications
Die casting machine parts(plungers,sleeves,goosenecks)
Features
Silicon nitride is a gray ceramics,it has excellent resistance to thermal shock
resistance,and it has a property that is a comparatively hard to
get wettability with molten metal.Silicon nitride ceramic is an inorganic material ceramic that does
not shrink when sintered. Silicon nitride is very strong,
especially hot pressed silicon nitride, which is one of the hardest
substances in the world. It has high strength, low density and high
temperature resistance.
Si3N4 ceramic is a covalent bond compound.The silicon atom is
located at the center of the tetrahedron. There are four nitrogen
atoms around it, which are located at the four vertices of the
tetrahedron, and then every three A tetrahedron shares the form of
an atom, forming a continuous and robust network structure in three
dimensions.
