Silicon Nitride(Si3N4)
Silicon nitride 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.
A.Thermal shock resistance
B.High temperature strength
C.Wear Resistance
D.Corrosion Resistance
E.Electrical Insulating properties
F.High Fracture Toughness
Main Applications
A. Molding mold parts(hot forging molds,various molds)
B. Casting parts(low pressure castings,various metal melting
furnace equipments)
C. Die casting machine parts(plungers,sleeves,goosenecks)
D. Welding machine parts(guide pin for resistance welding,guide
roll for steel pipe weldings)
E. Crusher parts(classifiers,airflow type crushers,beads mills)
F. Wear resistant parts(wire drawing machine guide rollers,motor
shafts,bearings,fishing line yarn paths,wire drawing capstans)
G. Semiconductor manufacturing equipment parts(stage parts,linear
motors parts)
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.
By utilizing these characteristics,it is used for components used
in harsh environments such as internal combustion engine parts of
automobiles and torch nozzles of welding machines,especially in
harsh environments.
In addition,utilizing high abrasion resistance and mechanical
strength to utilize the bearing parts,shafts,bearings and even the
effect of low dust generation to be used as parts of semiconductor
manufacturing equipment which is required for a clean environment.
