GE Advanced Ceramics BNC1 Boron Nitride (BN) Refractory Composite

 

Subcategory: Nitride

Material Notes:
Boron Nitride is a unique engineering material. It is a soft, machinable ceramic which can be combined with other refractory ceramics including Aluminum Oxide, Silicon Nitride, Aluminum Nitride, Mullite and Titanium Diboride. This results in composites which are machinable, thermal shock resistant, and chemically compatible in a wide range of environments. In combination with Titanium Diboride, for example, BN can be used as a heating source for the aluminum metallization of films and papers. BN composites are also used as break-rings in the horizontal continuous castings of steel and nozzles in rapid solidification processes. Other composite applications include the following:

  • High temperature refractory shapes
  • Glass forming tools and refractories
  • Molds, dies and refractories for metalforming
  • Furnace vents, stacks and fixtures

Grades BNC 1 & 2 offer excellent corrosion and wear resistance, have excellent thermal shock capability and low CTE, are non-wetting and are self lubricating.
