Ceramic Sintering Services

Powder Processing & Technology, LLC offers contract sintering services using Elevator or Tunnel Kilns. We load customer produced pre-pressed parts or 'green bodies' onto setter tile or place loose powders in saggers and sinter in air or nitrogen atmosphere. Sintering is an optimal process for creating sturdy powder or small, porous particles often surrounded by a coating. Sintered ceramic and ferrite powders are often used for:

  • Refractory applications
  • Electronic powders
  • Advanced ceramics

Please contact us for more information on our ceramic sintering services.
