Sintering boat

Annealing and sintering boats

Our combustion and sintering boats for continuous and batch furnaces are made of molybdenum, tantalum, niobium, tungsten, and numerous alloys. Using our components made of refractory materials, you will receive the highest quality combustion and sintering boats. The smoothness of their surfaces also guarantees that nothing will adhere to our combustion and sintering boats. In addition, we also offer various technologies and materials for coating the boats. This enables us to optimally adapt the surface of the combustion and sintering boats to your special requirements.

Your advantages at a glance:

  • High dimensional stability

  • Excellent creep
    resistance

  • High structural stability

  • Long service life

  • Customized design

  • Corrosion
    resistance

Enhanced dimensional stability using alloys

Using suitable alloys and optimized production processes, we can improve the properties of molybdenum. If you have special requirements regarding the dimensional stability of our combustion and sintering boats, then we recommend molybdenum-lanthanum and TZM.

Molybdenum-lanthanum

To achieve a particularly high level of ductility and creep resistance, we dope pure molybdenum with small quantities of La2O3. The stabilized microstructure and modified recrystallization behavior prevent the premature embrittlement and fracture of our furnace components.

Advantages of ML compared to pure molybdenum:

  • Higher recrystallization temperature
  • Elongated grain structure for higher ductility
  • Greater creep resistance
TZM

We strengthen the microstructure of pure molybdenum with titanium and zirconium to produce particularly robust materials. A Mo-Ti solid solution and Ti-Zr carbides ensure optimal strengths at temperatures up to 1400°C.

Advantages of TZM compared to pure molybdenum:

  • Better creep resistance
  • Higher recrystallization temperature
  • Greater high-temperature stability

Customized design

Sintering boat

We can customize our combustion and sintering boats to your individual requirements.

Our products are available in riveted, deep-drawn, and folded versions. Special versions are also possible in welded form depending on the choice of the material and design.

Whether remotely or on-site – we are here for you

Regardless of whether you need an entire hot zone or a spare part for your existing furnace, naturally we would be happy to install our products for you on-site. Our experts can also handle the inspection, maintenance, and optimization of your existing furnaces.

Remote service

Should repairs become necessary, that is a task that we would be happy to take care of for you on-site. If desired, our experts can also provide a remote service to support your needs. This can often quickly answer questions and resolve problems, significantly reducing downtimes.

Further products for high-temperature processes

Whether for annealing furnaces and soldering processes, coating systems, 3D printing sintering equipment, MIM furnaces, sintering furnaces, HIP processes or single crystal growing – our products made of molybdenum, tungsten, tantalum, and niobium can withstand the highest temperatures:
