silicon nitride ceramic components making process

  • Silicon Nitride - Ceramic Components, OEM Ceramic

    Silicon Nitride & Near-net Shaping. Sintered silicon nitride is extremely hard making any follow-up machining of components a challenge even for Ceramco's highly skilled experts. Ceramco mitigates the need for follow-up machining though the use of its near-net shaping process. Near-net shaping results in components very close to their final specification, also yielding little waste.
