These Boron Nitride composite ceramics have good resistance to creep, corrosion and thermal shock. They are suitable for almost all molten metals in high temperature.

Typical Applications

  1. Boron nitride continuous casting break rings
  2. Boron nitride side dams for thin-strip casting
  3. Boron nitride nozzles for amorphous and nanocrystalline
  4. Nozzles for powder metal atomization
