Product Detail

Si3N4 Silicon Nitride has the most versatile combination of mechanical, thermal, and electrical properties of any technical ceramic material. It is a high performance technical ceramic that is extremely hard and has exceptional thermal shock and impact resistance. It surpasses most metals high temperature capabilities and has a superior combination of creep and oxidation resistance. Additionally, its low thermal conductivity and high wear resistance make it an excellent material that can withstand the toughest of conditions in the most demanding industrial applications. Si3N4 Silicon Nitride is an excellent choice when high-temperature and high-load abilities are needed.

  • 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.
