Silicon nitride ceramic sealing ring

Silicon nitride ceramic sealing ring is a high-performance engineering ceramic sealing component made of silicon nitride (Si ∝ N ₄) material. Silicon nitride is a covalent compound with excellent mechanical properties and high-temperature stability. Its sealing ring inherits multiple advantages of silicon nitride, such as high hardness, high wear resistance, low density, good thermal shock resistance, and corrosion resistance. Silicon nitride ceramic sealing rings can maintain stable performance in extreme environments and are an ideal alternative to traditional sealing materials.
