Boron nitride in powder metallurgy
In powder metallurgy, boron nitride is used as a protective, release, and coating material to prevent reactions between metal and tool surfaces.
Its high-temperature resistance up to 2200 °C, excellent non-wetting properties, and chemical resistance make it an indispensable material in thermal and forming processes.

Frequently Asked Questions
Why is boron nitride an ideal material for powder metallurgy?
In powder metallurgy and especially in metal atomization, work is often carried out at high temperatures, in complex atmospheres and with sensitive material systems. Boron nitride is the ideal solution for these harsh conditions, as it is extremely chemically resistant to aggressive alloy components and can even be used without extensive preheating. This ensures an excellent service life for the nozzles, even with very large casting quantities.
How do boron nitride nozzles improve the quality of the metal powder produced?
The use of special high-performance ceramics such as HeBoSint® SL-N 300 guarantees that the metal powder produced is of extremely high purity. A key technological advantage of these nozzles is that both the particle shape and the particle size distribution (PSD) can be precisely controlled and influenced during atomisation. This reliably ensures consistent, top-quality results in every single batch.
What are the economic benefits of using HeBoSint® SL-N 300 in metal atomisation?
To operate the metal atomisation process profitably and efficiently, the energy used must be utilised optimally, powder yield maximised and waste minimised. This is precisely where HeBoSint® SL-N 300 comes into its own: the nozzles enable maximum powder yields, drastically reduce unwanted waste and help to avoid long and costly downtimes or maintenance periods. Overall, this leads to significantly reduced process costs.
