Product Description
 | Insulating Ceramic Part Hot-pressed Si₃N₄: higher thermal conductivity but limited to simple shapes Reaction-bonded Si₃N₄: porous, low toughness, only for low-load corrosion service |
Silicon Nitride Ceramic ring Applications: wear flanges for bead mills, insulating support for semiconductor high-temperature chamber, pump sealing rings, thermal treatment fixtures, metallurgical locating components. |
|
 | Si3N4 Ceramic Flange: High fracture toughness: 6–9 MPa·m¹ᐟ², resistant to impact and sudden crack failure; maintains high strength up to 1200℃ |
Si3N4 Ceramic Flange Ring With 3 Mounting Lugs: It features a 3-lug structure with mounting holes, used for equipment positioning, sealing, wear resistance, heat insulation and insulating support. It is a custom structural ceramic part. |  |
