GE Advanced Ceramics AC6043 Aluminum Nitride/Boron Nitride Composite


Subcategory: Nitride; Ceramic Matrix Composite

Key Words: BN, AlN

Material Notes:
AlN/BN. Density is 85-90% of theoretical. Sonic Modular1 is 4 to 9 x 10^6 psi.

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.

BN composites are also used:

Break-rings in the horizontal continuous castings of steel, and nozzles in rapid solidification processes

High temperature refractory shapes

Glass forming tools and refractories

Molds, dies and refractories for metalforming

Furnace vents, stacks and fixtures.

Information provided by GE Advanced Ceramics.

Available Properties
  • Flexural Strength
  • CTE, linear 20°C
  • Thermal Conductivity
