Product Detail

Si3N4 Silicon Nitride Ceramic is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts with a striking appearance. The very high quality bodies developed for these demanding high reliability applications are available today and can be used in many mechanical, thermal and wear applications. What's more, Si3N4 Silicon Nitride is an electrical insulator and is not wet by nonferrous alloys. Silicon Nitride Ceramic is a rather expensive material, but it’s performance to cost benefit ratio is excellent in the applications where it can outperform the normally utilized materials with long life and very reliable low maintenance operation.

  • Ceramic Welding Roll

    Ceramic Si3N4 Welding Rolls for Steel Tube Industry

    silicon nitride ceramics is an inorganic non-metallic material. It is a super-hard material, which has lubricity and is wear-resistant; except for hydrofluoric acid, it does not react with other inorganic acids. It is highly corrosive and resistant to oxidation at high temperatures. Moreover, it can resist high thermal shocks. It will not crack when heated to over 1,000°C in the air, cooled rapidly and then heated rapidly. Because of the excellent characteristics of Si3N4 ceramics, it’s often used to manufacture bearings, turbine blades, mechanical seal rings, permanent molds and other mechanical components. In the field of welding of copper stainless, and aluminum tubes, silicon nitride ceramic rolls have natural advantages.
