product_detail

Graphite boat is a precision graphite carrier used to hold wafers, powder and workpieces under vacuum and high temperature. Dongguan Jiecheng Graphite Products Co., Ltd. supplies custom graphite boats for thermal processing lines.

Key Features It has excellent thermal conductivity and uniform heat distribution. Low thermal expansion keeps stable dimensions during thermal cycles. Good chemical inertness avoids reaction with most materials. High-purity grades have low ash content to prevent product contamination. Precision grooving and flatness can be achieved by CNC machining.

Graphite Boat

Typical Applications

  • Powder metallurgy and cemented carbide sintering
  • Lithium battery cathode and anode material sintering
  • Ceramic and magnetic material heat treatment
  • Laboratory high-temperature testing and analysis
  • Vacuum brazing and annealing processes

Jiecheng Graphite customizes the slot layout, size and structure of graphite boats. Material test reports are available for each batch.
