High Polished Silicon Nitride Ceramic Cylinder Piston Plunger Shaft For Pump
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.
