Boron nitride nozzles made of hot pressed boron nitride ceramics have outstanding thermal shock resistance, crack or break will not happen when boron nitride nozzles undergo sudden heating or cooling. The ceramic nozzles have good temperature resistance up to 2100℃ (under inert gas protection). Boron nitride ceramic nozzles are widely applied for metal powder gas atomization because they have no reaction or wetting with molten metals.

Boron nitride (BN) nozzles made of hot pressed boron nitride ceramics have outstanding thermal shock resistance, crack or break will not happen when boron nitride nozzles undergo sudden heating or cooling. The ceramic nozzles have good temperature resistance up to 2100℃ (under inert gas protection). Boron nitride ceramic nozzles are widely applied for metal powder gas atomization because they have no reaction or wetting with molten metals. 


Our company develops a variety of material formula for boron nitride nozzles according to various gas atomization processes and powder materials to meet the needs of different users, we will give suggestion for material selection when inquiry.





Feature of boron nitride nozzles


  • Good resistance to thermal shocks

  • Good resistance to high temperature in vacuum&gas protection condition

  • Will not react with molten metals

  • Non-wetting with molten metals and the nozzles will not be stuck

  • Low thermal expansion coefficient
