| Hot pressing has a limited field of application for such materials, which do not sinter to high densities due to low diffusion coefficients or for cases where a pore-free state is required (for optimum mechanical, thermal or optical properties). With this process only parts with simple shapes like plates, blocks, cylinders can be manufactured easily. With a highly sophisticated design of pressing dies also more complex shapes can be produced. |

| Specifications︰ | Available pressing force: 50 to 10000 kN at max. 2500°C, applicable for components of max. Ø 600 mm. |
| Advantages︰ | Application of hot pressing in the field of ceramics
include:
· Silicon nitride, mixed ceramics of Al2O3, TiC/TiN and sialon for cutting tools, components of heavy-duty valves, bearings, wear parts for process technology.
· PLZT (lead-lanthan-zircon-titanate) and other high developed functional ceramics (O2 atmosphere)
· Boron carbide (B4C) for extremely wear resistant parts and armors.
· SiC whisker reinforced Al2O3 for cutting tools
· MMC- and CMC materials, composite materials
· Sputter targets
Hotpressing technology is applied variously in fundamental research and production.
