Si3N4 Silicon Nitride Ceramic M8 Thread Welding Location Dowel Pin

1 . Descriptions:

Silicon Nitride is a man made compound synthesized through several different chemical reaction methods.Parts are pressed and sintered by well developed methods to produce a ceramic a unique set of outstanding propeties.The material is dark gray to black in color and can be polished to a very smooth reflective surface,giving parts with a striking appearance.

Silicon nitride exceeds other cermaic materials in thermal shock resistance.It also offers an excellent combination of low density,high strength ,low thermal expansion and good coorosion resistance and fracture thoughness.

Silicon nitride has been used in a number of industrial applications,such as engine components,bearing and cutting tools.

Si3N4 Ceramic is one kind of technical ceramic materials which has good comprehensive properties for different applaictions.It mechanical strength can be kept up to 1200℃.Its hardness and wear resistance performance ranks high among all technical creamic materials.Its has high electrical resistivity,high dielectric constant and low dielectric loss,is a choice for electrical insulation.Futrthmore,it has good chemical stability and resistance to oxidation.
