Boron nitride in sintering technology
In sintering technology, components are compacted and shaped at temperatures of up to 2200 °C. In this process, chemical reactions, friction, and thermal stress interact directly.
Traditional materials such as graphite, aluminum oxide (Al₂O₃), or zirconia (ZrO₂) often cannot meet these requirements. Products made of hexagonal boron nitride, however, can! They combine reliable release properties, longer service life, and clean processing under extreme process conditions.
Typical applications:
- Boron nitride carrier plates, charging plates, and crucibles
- Coating of sintering molds, press dies, and support systems
- Separating and protective layers in the manufacture of high-performance ceramics, cemented carbides, or powder metallurgy components
- Boron nitride powder and additives for optimizing flow behavior and reducing friction during compaction
- Embedding powder as a loading aid
