In the area of sintering technology both continuous and batch high-temperature furnaces are used.
Continuous Furnaces (pusher or walking-beam) usually have heating elements made of molybdenum or tungsten. This type of furnace is used in sintering processes up to around 1900°C. The sintering boats, trays and base plates are made of pure molybdenum, or preferably of the PLANSEE high-performance material ML.
Batch Furnaces for sintering processes are extremely flexible and permit temperatures of up to 2500°C. Molybdenum- and tungsten-based materials are used for heating elements, heat shields and charge carriers. Such furnaces can be operated under vacuum or with a protective gas atmosphere.
Major Applications:
- Sintering of fuel pellets (UO2 and mixed-oxide) for nuclear power
- Sintering of translucent Al2O3 tubes for lighting technology
- Sintering (firing) of technical ceramics (multi-layer printed circuit boards, IC housings etc.)
- Sintering of rare-earth magnets
- Sintering of tantalum capacitors
- Sintering of metals and ceramics
- Sintering of refractory metals
The PLANSEE Product Range:
- Development, design and production of complete hot zones
- Production of sintering boats, base plates, stacking sheets, spacers and charge carriers of molybdenum, TZM and MLR
- Production of molybdenum and tungsten components (heating elements, heat shields, charge racks and accessories)
- Rebuilding and upgrading of existing furnaces
- Bespoke components to customer drawings
- Spare parts and semi-finished products (sheets, wires, rods and fasteners)
